Selection Guide

Choose the AD7382BCPZ when you need high-resolution (16-bit) dual-channel simultaneous sampling at high speed (4 MSPS). It is ideal for motor control, power monitoring, and data acquisition systems where phase accuracy is critical. If you can accept lower resolution, the AD7381BCPZ (14-bit) is a cost-effective drop-in alternative. For applications requiring more channels, consider the AD7381-4BCPZ (quad, 14-bit) or AD7682BCPZ (quad, 16-bit, but slower). The AD7380BCPZ is a direct drop-in with identical specs, suitable for designs needing a second source.

Design Notes

The AD7382BCPZ requires a clean 3.3V analog supply (VDD) and a separate digital supply (VIO). Use low-ESR ceramic capacitors (e.g., 0.1uF and 10uF) placed close to the VDD and VIO pins to decouple high-frequency noise. The reference input (VREF) should also be decoupled with a 10uF capacitor to ensure stable operation.

For optimal performance, place the AD7382BCPZ close to the signal source to minimize trace inductance. Use a solid ground plane and avoid routing digital signals near the analog inputs. The SPI lines (SCLK, SDI, SDO, CS) should be kept short and shielded if necessary to prevent crosstalk.

Ensure that the reference voltage is within the specified range and is stable. Do not exceed the absolute maximum ratings for VDD and VIO. Also, verify that the SPI clock frequency does not exceed the maximum specified in the datasheet to avoid data corruption.
