Description
The AD7323BRUZ is a 12-bit, 4-channel successive approximation (SAR) analog-to-digital converter (ADC) from Analog Devices. It supports bipolar input ranges (±10V, ±5V, ±2.5V) and unipolar ranges (0–10V, 0–5V), selected via software. Key features include:
- High throughput: 500 kSPS
- On-chip reference (2.5V) with external reference option
- SPI-compatible serial interface
- Low power: 13.5 mW at 500 kSPS
The ADC includes per-channel programmable input ranges, a sequencer for automated channel scanning, and ±0.5 LSB INL/DNL for high accuracy. It operates from ±12V/±15V supplies and is housed in a TSSOP-16 package.
Applications include industrial control, data acquisition, and instrumentation. Its flexible input ranges and integrated features make it suitable for multi-channel systems requiring precision and speed.
For detailed specs, refer to the datasheet on Analog Devices' website.
