概述
Description
The AD7656BSTZ is a 16-bit, simultaneous sampling SAR ADC from Analog Devices. It features six channels, each capable of sampling at 250 kSPS, making it ideal for multi-channel data acquisition systems.
Key features:
- 16-bit resolution with ±2 LSB INL.
- True bipolar input ranges (±10V, ±5V, ±2.5V).
- Low power consumption (50 mW per channel at 250 kSPS).
- SPI/QSPI-compatible serial interface.
- On-chip reference & buffer for simplified design.
Applications include motor control, power monitoring, and medical instrumentation. The BSTZ suffix denotes a LQFP-64 package with industrial temperature range (-40°C to +85°C).
For detailed specs, refer to the datasheet.
