Selection Guide

Choose the AD7795BRUZ when you need a 16-bit sigma-delta ADC with six differential inputs and an on-chip in-amp for direct sensor interfacing. It is ideal for multi-channel precision measurement applications such as temperature, pressure, and weigh scales.

Design Notes

The AD7795BRUZ operates from a single 2.7V to 5.25V supply. Use separate analog (AVDD) and digital (DVDD) supplies to minimize digital noise coupling. Decouple each supply pin with a 10µF tantalum capacitor in parallel with a 0.1µF ceramic capacitor placed as close to the pin as possible. The power-down mode reduces current to 1µA, which is useful for battery-powered applications.

For optimal noise performance, use a solid ground plane and separate analog and digital ground planes if possible. Connect the ground planes at a single point near the ADC. Keep analog input traces short and shielded from digital signals. Place the reference decoupling capacitors close to the REFIN pins. The exposed pad (if present) should be soldered to the ground plane for thermal and electrical performance.

Ensure the reference voltage is stable and low noise. The internal reference is suitable for most applications, but for higher accuracy, use an external reference. Avoid driving the analog inputs beyond the supply rails. The PGA gain setting affects the input range; ensure the input signal is within the common-mode range. Also, the serial interface should be configured correctly to avoid data corruption.
