Overview
Description
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.
Equivalent
- AD7656-1BSTZ (similar with minor spec differences)
- AD7657BSTZ (faster throughput, 16-bit, 6-channel)
- LTC2387-16 (16-bit, 8-channel SAR ADC from Analog Devices/LTC)
- ADS8568 (16-bit, 8-channel SAR ADC from TI)
Check datasheets for exact compatibility in your application.
Pinout
- Pin Count: 64-pin (LQFP package)
- Key Functions:
- 6 analog inputs (IN1–IN6) for simultaneous sampling.
- SPI/QSPI-compatible serial interface for data output.
- Reference inputs (REFIN/REFOUT) for internal/external reference options.
- Control pins (CONVST, BUSY, RANGE) for conversion start, status, and input range selection.
- Power supply pins (AVDD, DVDD) for analog (5V) and digital (2.7–5.25V) operation.
Designed for high-speed, multi-channel applications like power monitoring and industrial systems.
Application
- Industrial Automation: Process control, PLCs, and motor control.
- Medical Equipment: Patient monitoring and imaging systems.
- Power Monitoring: Energy metering and smart grid systems.
- Test & Measurement: Data acquisition and instrumentation.
- Defense/Aerospace: Radar and communication systems.
Its simultaneous sampling, low power, and robust performance make it ideal for multi-channel systems demanding accuracy and speed.
