Overview

Pinout

The AD7787BRMZ is a 24-bit sigma-delta ADC with 10 pins in an MSOP package.
Key Functions:
- Analog Inputs: Differential (AIN+, AIN-) or pseudo-differential (AIN, GND).
- Reference Input (REFIN): External reference voltage (typ. 2.5V).
- Digital Interface: SPI-compatible (SCLK, DOUT/RDY, DIN, CS).
- Power Supply: Operates from 2.7V to 5.25V (AVDD, DVDD).
- Output Data Rate: Programmable (4.17Hz to 470Hz).
- Low Power: Suitable for battery-powered applications.
Pinout Summary:
1. AIN+ – Positive analog input
2. AIN- – Negative analog input
3. REFIN – Reference input
4. GND – Ground
5. CS – Chip select (SPI)
6. SCLK – Serial clock (SPI)
7. DOUT/RDY – Data output/ready signal
8. DIN – Serial data input (SPI)
9. AVDD – Analog supply
10. DVDD – Digital supply
Compact and versatile, it’s ideal for precision sensor measurements.
