AD5372BSTZ - 32-Channel 16-Bit Serial DAC | Analog Devices
MPN: AD5372BSTZ ✓ نشطAD5372BSTZ نظرة عامة
A digital-to-analog converter (DAC) is an electronic component that converts digital binary data into an analog voltage or current. The AD5372BSTZ belongs to the family of voltage-output DACs, which are essential in applications requiring precise analog control from digital systems, such as industrial automation, instrumentation, and communication systems. As a multi-channel DAC, it integrates 32 individual converters in a single package, reducing board space and simplifying system design.
Key features of the AD5372BSTZ include 16-bit resolution, 32 independent DAC channels, and a serial interface compatible with SPI/QSPI/MICROWIRE. Each DAC has a buffered output capable of driving loads directly, and the gain and offset of each channel can be independently trimmed to remove system errors. The device operates from a single 2.5V to 5.5V supply, with a reference voltage range of 2V to 5V, and provides a nominal output span of 4× VREF.
The AD5372BSTZ uses a resistor-string architecture with an output buffer for each channel, ensuring monotonicity and low glitch energy. The serial interface supports daisy-chaining, allowing multiple devices to be controlled with a single data line. The device includes a power-on reset that clears all DAC registers to zero-scale, and a CLR pin that resets outputs to zero-scale or midscale. The LQFP package provides good thermal performance and is suitable for surface-mount assembly.
Typical applications include automatic test equipment (ATE), optical network control, instrumentation, and industrial process control. The 32 channels and 16-bit resolution make it suitable for systems requiring many precise analog outputs, such as multi-axis positioning, programmable voltage sources, and calibration equipment.
When designing with the AD5372BSTZ, ensure adequate decoupling on the AVDD and DVDD supplies, and place the reference decoupling capacitor close to the REFIN pin. The serial clock frequency should be limited to 50 MHz to ensure reliable communication, and the SYNC pin must be held low during data transfer.

ملاحظات التصميم
Decouple AVDD and DVDD with 10 µF and 0.1 µF capacitors placed close to the pins. Use separate analog and digital ground planes to minimize noise coupling. The reference input should be decoupled with a 1 µF capacitor to REFIN and GND.
For optimal performance, place the AD5372BSTZ on a PCB with a solid ground plane. Keep the serial interface traces short and avoid routing them near high-speed digital lines. The LQFP package has exposed pads; ensure proper soldering for thermal and mechanical reliability.
Ensure the SYNC pin is held low during data transfer and that SCLK frequency does not exceed 50 MHz. The CLR pin can be used to reset outputs to zero-scale or midscale; tie it high if not used. Avoid floating the RESET pin; connect it to DVDD through a pull-up resistor.
