Description
The AD7689BCPZRL7 is a 16-bit, 8-channel, successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It features high accuracy (up to ±0.5 LSB INL), low power consumption (1.5 mW at 100 kSPS), and a flexible serial interface (SPI/QSPI/MICROWIRE).
Key specifications:
- Resolution: 16 bits
- Channels: 8 single-ended or 4 differential
- Throughput: Up to 250 kSPS
- Supply Voltage: 2.3V to 5.5V
- Package: 20-lead LFCSP (4mm × 4mm)
The ADC includes an internal reference (2.5V) and supports external references. It operates over a wide temperature range (-40°C to +85°C), making it suitable for industrial, medical, and instrumentation applications.
The BCPZRL7 variant includes a lead-free, RoHS-compliant package with a reel packaging option for automated assembly.
For detailed usage, refer to the datasheet for timing diagrams, register configurations, and layout guidelines.
