RC4559P Description

The RC4559 is a dual operating amplifier with exceptional performance. Low-noise signal applications, such as audio preamplifiers and signal conditioners, benefit greatly from this amplifier’s high common-mode input voltage and lack of latch-up. This amplifier’s output drive capabilities and guaranteed dynamic performance are exceptional compared to standard amplifiers. The specified temperature range for the RC4559 is from 0 to 70 degrees Celsius.

RC4559P Detailed Features

The RC4559 is a differential pair of operational amplifiers (op-amps) with matched gain and offset. Because of this, it can be used in active filters, mixers, and oscillators, all of which often use several op-amps in a single package.

The RC4559 has a unity-gain bandwidth of at least 0.3 MHz, making it one of its most distinguishing features. This number represents the highest frequency at which the op-amp can maintain unity gain without introducing unacceptable distortion.

An additional strength of this op-amp is its minimum slew rate of 1.5 V/ns, which is the maximum rate at which the output voltage can fluctuate in response to a step input. In situations when high-frequency transmissions are present, this value is crucial.

The maximum equivalent input noise voltage of the RC4559 is only 2 V/Hz (20 Hz to 20 kHz). This number represents how much noise an op-amp adds to a signal during amplification. Having a lower value here improves the amplifier’s signal-to-noise ratio.

The RC4559 is also notable since it does not need frequency correction. This allows its usage in situations where stability is paramount without requiring extra components or fine-tuning.

The op-amp has been made to directly replace the Raytheon RC4559 in any application where that part is used.

The RC4559 also accepts input signals that are either higher or lower than the supply voltage, thanks to its broad common-mode voltage range. The low power consumption of the op-amp makes it ideal for use in portable devices that run on batteries.

At the end of the day, the RC4559 is built to tolerate high voltage transients without triggering a self-sustaining current that may destroy the device because of a feature called “latch-up free.”

RC4559 Specifications

One chip of the RC4559 contains a high-performance amplifier with two independent channels. With an ECCN of EAR99, it demonstrates conformity with EU RoHS regulations. HTS code 8542.33.00.01 indicates an operational condition of “active.” It lacks PPAP support and does not meet automotive quality standards.

The RC4559 requires a dual power supply with voltages between 5V and 15V to function. The maximum quiescent current is 5.6 mA at 15V, while the maximum power dissipation is 500 mW. Maximum input offset voltage is 6 mV at 15V, maximum input offset current is 0.1 A at 15V, and maximum input bias current is 0.25 A at 15V.

Amplifier’s normal slew rate is 2 V/s at 15V, and its CMRR is at least 80 dB and typically sits in the region of 85 dB. The standard shut down support is absent, and the product’s bandwidth is only 4 MHz.

The RC4559 has a through-hole mounting method with 8 pins, and it can function at temperatures between 0 and 70 degrees Celsius. It comes in a tube with maximum outside measurements of 10.16 mm x 6.6 mm x 5.08 mm. Through-hole leads and a maximum package height of 5.08 mm are specified. Standard packaging is DIP, but the PDIP used by the provider is the result of eight revisions to the printed circuit board.

The RC4559 has a low input offset voltage and a low input bias current, making it a high-performance amplifier. It has a high gain bandwidth product and CMRR and can run on two independent power sources. The DIP packaging and through-hole mounting technique make it versatile.

What Are Operational Amplifiers – Op Amps Dual High Performer and How Does It Work

A dual high-performance operational amplifier (Op Amp) takes in two voltage inputs and outputs a voltage proportionate to the difference between them. High-performance op amps, known as “Dual High Performers,” bundle not one but two amplifiers into a single compact package, making them perfect for situations that call for amplification on several levels.

In its most basic form, an operational amplifier (op amp) has three connections: an inverting input (-), a non-inverting input (+), and an output. The op amp creates an output voltage that is proportionate to the voltage differential between the two input terminals. The feedback resistor ratio establishes the gain of the operational amplifier.

Two amplifiers, or “op amps,” are contained in a single “Dual High Performer” box, with the latter’s two amplifiers capable of either independent operation or interconnection. Because of their independence from one another, amplifiers can serve various purposes in a given circuit. Op-amps find widespread use in audio processing, filter design, and other areas of signal processing.

For instance, the RC4559 is an op amp that excels in both gain and bandwidth while maintaining a low input offset voltage and input bias current. With a typical slew rate of 2 V/s at 15 V, it runs on a dual power supply and is extremely efficient. It has an extensive common-mode voltage range and is packed in a through-hole mounting type with 8 pins.

In conclusion, operational amplifiers (op amps) with dual gain stages are extremely flexible electrical components with widespread application in signal processing and other circuits requiring multiple amplifiers. The voltage difference between the input terminals is amplified to generate an output voltage proportionate to the input voltage.
