Selection Guide

Choose the AD5381BSTZ-3 when you need a 40-channel, 12-bit DAC operating from a 3 V supply, ideal for low-power multi-channel systems. If your system uses a 5 V supply, the AD5381BSTZ-5 is a drop-in alternative. For higher resolution (14-bit) with the same channel count, consider the AD5371BSTZ, but note it may have different settling time and interface requirements. If you need fewer channels (32) but higher resolution, the AD5372BSTZ is suitable. The AD5380BSTZ-3 offers 14-bit resolution with 40 channels but may have different specifications. Evaluate your supply voltage, resolution, and channel count requirements to select the best fit.

Key Differentiators

40-channel density in a 100-lead LQFP (vs AD5372BSTZ)
12-bit resolution with 8 µs settling time (vs AD5371BSTZ)
3 V single-supply operation (vs AD5381BSTZ-5)

Design Notes

The AD5381BSTZ-3 requires a 3 V analog supply (AVDD) and a digital supply (DVDD). Ensure adequate decoupling with 0.1 µF and 10 µF capacitors close to the AVDD and DVDD pins. The reference pin (REFIN/REFOUT) should be decoupled with a 1 µF capacitor to ground. Proper power supply sequencing is recommended to avoid latch-up.

For optimal performance, place the AD5381BSTZ-3 on a PCB with a solid ground plane. Keep analog and digital grounds separate and connect them at a single point. Route analog output traces away from digital signals to minimize noise coupling. Use short, wide traces for power and ground to reduce inductance.

When using the serial interface, ensure the SER/PAR pin is tied high and the SPI/I2C pin (Pin 97) is tied low for SPI mode. Do not operate the device with a 2.5 V reference if you require full accuracy, as the datasheet warns of degraded accuracy and limited input code range. Always verify the reference voltage setting in the control register.
