AD5542ABCPZ-REEL7 General Description

Single supply 2.7 V to 5.5 V digital-to-analog converters (DAC) with 12-bit and 16-bit resolution, serial input, and unbuffered voltage output are provided by the AD5512A/AD5542A. With a defined operating temperature range of 40 to +85 degrees Celsius (AD5542A) or 40 to +125 degrees Celsius (AD5542A), the DAC’s output is guaranteed to be monotonic over the whole range from 0 V to VREF, with an accuracy of 1 LSB INL at 16 bits (AD5512A). The AD5512A/AD5542A are suited for high-speed open-loop control thanks to their unbuffered outputs and 1 s settling time with low offset errors.

The AD5512A and AD5542A have a VREF output swing because they operate in a bipolar mode. Reference and analog ground pins of the AD5512A/AD5542A have Kelvin sense connections to lessen the need for careful configuration. The AD5512A/AD5542A come in a 16-lead LFCSP package, while the AD5542A is also offered in 10-lead and 16-lead LFCSP and TSSOP packages.

AD5542ABCPZ-REEL7 Theory of Operation

DACs with voltage outputs and a single serial input, the AD5512A/AD5542A, have a bit depth of 12 bits and 16 bits, respectively. They require a power input between 2.7 V and 5 V to function, with a typical consumption of 125 A at the higher voltage. These devices accept serial input via a 3- or 4-wire interface and store data in 12-bit (AD5512A) or 16-bit (AD5542A) words. These components are built with a power-on reset feature to guarantee a consistent initial condition after being powered on. The output is zeroed out in bipolar mode and set to midscale in unipolar mode. Reference and analog ground Kelvin sensing connections are built into the AD5512A/ AD5542A.

AD5542ABCPZ-REEL7 Serial Interface.

The AD5512A and AD5542A can be controlled over a three- or four-wire serial interface. This interface, which can support clock frequencies of up to 50 MHz, is compatible with the SPI, QSPI, MICROWIRE, and DSP interface standards. A “construction ecosystem” is a group of people who work in the construction industry. The chip select input, or CS, frames the input data.

Data on the CS line is shifted in sync with the SCLK and captured in the input register at the rising edge of the clock signal when it transitions from high to low. In words of 12 bits (AD5512A) or 16 bits (AD5512B), the most significant bit of the data is loaded first (AD5542A). After loading 12 (AD5512A) or 16 (AD5542A) data bits into the serial input register, the shift register’s contents are sent to the DAC through a low to high transition on CS. Only when CS is low can data be loaded onto the component.

A “construction ecosystem” is a group of people who work in the construction industry. LDAC should be kept at a high level in writing data to the shift register. Instead, the DAC can be updated concurrently by setting LDAC to a continually low value. When LDAC is held in a low state all the time, the rising edge of CS loads the data onto the DAC.

Unipolar Output Operation

These DACs can drive unbuffered loads with a resistance of sixty thousand ohms. Low supply current, typically 300 A, and a low offset error result from unbuffered operation. The unipolar output swing of the AD5512A/AD5542A is 0 V to VREF.

Output Amplifier Selection

“ecosystem” refers to a group working in the construction industry. This yields the VREF output. Because the amplifier’s output swing typically does not include the negative rail, or AGND, in a single-supply application, choosing an appropriate op amp may be trickier. Unless the program uses codes very close to zero, this may cause a slight drop in the promised performance. To avoid the requirement for output offset trimming, the chosen op amp must have a very low offset voltage (the DAC LSB is 38 V for the AD5542A with a 2.5 V reference).

“ecosystem” refers to a group working in the construction industry. Rail-to-rail input and output performance is necessary. The op amp’s slew rate should not slow down the DAC’s settling time for quick settlement. The output impedance of the DAC is constant and code-independent; however, the output amplifier’s input impedance should be as high as possible to reduce gain mistakes. The amplifier’s bandwidth should be at least 1 MHz at 3 dB. The output takes longer to settle because the amplifier introduces a second time constant to the system. When the amplifier’s bandwidth increases, the combined DAC and amplifier’s effective settling time is shortened by 3 dB.

Reference and Ground

Because the input impedance varies from code to code, a low impedance source must power the reference pin. The AD5512A and AD5542A use a voltage reference between 2 V and VDD to function. Reduced precision results from references below 2 V. The reference sets the DAC’s maximum output voltage. The AD5512A/AD5542A has connections for Kelvin sensing for maximum efficiency. Tie the lines near to the package to reduce voltage dips between the package leads and the internal die if the application doesn’t need separate force and sense lines.
