AD8606ARZ Description

Electronic components are the unsung heroes that keep our technological world ticking around. Due to their essential role in signal amplification and processing, many electrical applications would not function without amplifiers. The Analog Devices AD8605, AD8606, and AD8608 amplifiers are built to provide unmatched accuracy and performance in various settings. These rail-to-rail input and output amplifiers have an excellent blend of low noise, low offsets, broad bandwidth, and fast speed, making them suitable for various applications. In this article, we will examine the characteristics and uses of these amplifiers in further detail, illuminating for you why they are the preferred option among engineers and designers throughout the globe.

AD8606ARZ General Description

The AD8606ARZ is a family of single-supply, rail-to-rail amplifiers with a choice of single, dual, or quad inputs and outputs. They have a wide signal bandwidth, low input voltage and current noise, and low offset voltage. DigiTrim® is a patented method of trimming developed by Analog Devices, Inc., that allows for high precision without needing a laser. These amplifiers are applicable in many contexts thanks to their low offsets, low noise, very low input bias currents, and high speed. The combination of performance characteristics is useful in various applications, including filters, integrators, photodiode amplifiers, and high impedance sensors. The high frequency range and minimal distortion are useful in audio and other ac applications.

These amplifiers have many uses, including optical control loops, portable and loop-powered instruments, and portable audio amplification. All three of the AD8605, AD8606, and AD8608 are guaranteed to function from -40 degrees Celsius to +125 degrees Celsius, a range covering most typical industrial environments. The AD8605 can be purchased in either a 5-ball WLCSP or a 5-lead SOT-23 package. There are three different surface-mount options for the AD8606 dual: an 8-lead MSOP, an 8-ball WLSCP, and a thin SOIC. Two different 14-lead packages are on hand for the AD8608 quad: a wide 14-lead SOIC and a narrow 14-lead TSSOP. There is no smaller footprint for an op amp that can be surface-mounted than the 5-ball or 8-ball WLCSP. Tape-and-reel is the only medium for purchasing WLCSP, MSOP, SOT-23, and TSSOP variants.

Features of the AD8606ARZ Amplifiers

● Low Offset Voltage

The low offset voltage of the AD8606ARZ amplifiers is one of their most notable characteristics, with a maximum of 65 V stated. When the input voltage to an amplifier is zero, an offset voltage, typically a DC value, emerges at the amplifier’s output. The more stable the offset voltage, the more accurate the amplifier’s measurements can be.

● Low Input Bias Currents

The highest input bias current for the AD8606ARZ amplifiers is only 1 pA. Amplifiers have what are called input bias currents, which are the currents that either enter or leave the amplifier through the input terminals. When the input bias current is low, the amplifier is less likely to distort the input signal, allowing for more accurate readings.

● Low Noise

Noise in the AD8606ARZ amplifiers is specified to be just 8 nV/Hz. Noise, or random oscillations in an amplifier’s output, can affect the reliability of the readings. An amplifier needs to have a low noise level to make precise measurements.

● High Bandwidth

The AD8606ARZ amplifiers are characterized by a broad signal bandwidth specified to be 10 MHz. The effective frequency range over which an amplifier may function is known as its bandwidth. The amplifier can handle higher-frequency signals more effectively when it has a larger bandwidth.

Applications Information

● Output Phase Reversal

When a voltage greater than the maximum input common-mode voltage drives the input, the amplifier experiences phase reversal, which manifests as a polarity flip at the device’s output. The amplifier may be irreparably damaged, and feedback loop lockups may occur if the phase is reversed. No matter how much more than 2 V the input voltage is above the supply voltage, the AD8605 does not reverse its phase.

● Maximum Power Dissipation

As the die temperature of an integrated circuit rises due to the dissipation of power, the IC’s behavior and the performance of its associated application circuit can be adversely affected. The AD8605, AD8606, and AD8608 can withstand a maximum junction temperature of 150 degrees Celsius. If the device’s temperature rises above the safe range, it could be damaged or rendered useless.


The total harmonic distortion is the spectral ratio of the input signal to all of the harmonics. Harmonic distortion causes unpleasant acoustic distortions in audio systems and introduces flaws into precision measurements. Total harmonic distortion is minimal in the AD860x. With a load of 10 k and set to positive unity gain, the worst-case configuration for the AD8605, this is the worst possible situation.

● Total Noise Including Source Resistors

Because of its low input current noise and input bias current, the AD860x is ideally suited as an amplifier for circuits utilizing photodiodes and other high-impedance input sources. If the source resistance is 1 k, the input offset voltage will rise by less than 0.5 nV at ambient temperature and rise to 10 nV at 85 °C.

● Channel Separation

Inverse crosstalk, also known as channel separation, quantifies the degree to which one amplifier’s output is fed into another amplifier’s output on the same integrated circuit. In most cases, the AD8606’s two amplifiers can boost ac signals separately thanks to a channel separation of more than 160 dB up to 1 GHz.

● Capacitive Load Drive

The AD860x is capable of driving high capacitive loads without causing oscillations. The AD8606’s output in response to a 200 mV input signal is displayed in Figure 50. The amplifier is set up in positive unity gain, the most stable configuration, and drives a 1000 pF load at its output. Further circuitry may be necessary to achieve unity gain when driving bigger capacitive loads.

● Light Sensitivity

The active side of the AD8605ACB is designed to make contact with solder bumps; hence the chip is simply a silicon die with additional post-fabrication dielectric and intermetallic processing. This form of packaging leaves the die vulnerable to photoelectric effects from outside light. The input bias current (IB) parameter is the sole one affected by direct illumination of the AD8605ACB package when installed on conventional PCB material, as determined by an examination of the package’s light sensitivity.

Light from low-intensity (0.1 mW/cm2) ambient sources does not affect electrical performance.

● Instrumentation Amplifiers

Because of its low offset voltage and low noise, the AD8605 is a fantastic amplifier for measuring instruments. Different amplifiers are frequently utilized in high precision circuits to increase the common-mode rejection ratio.

● DAC Conversion

Because of its low input bias current and offset voltage, the AD8605 is ideally suited for use as a current output DAC buffer.
