Description

The AD7683ARMZ is a 16-bit, successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It features:
- Resolution: 16-bit
- Throughput: Up to 250 kSPS
- Input Range: ±VREF (bipolar) or 0 to VREF (unipolar)
- Low Power: 1.5 mW at 250 kSPS
- Interface: SPI-compatible serial interface
- Package: 10-lead MSOP
It operates from a 2.3V to 5.5V supply, making it suitable for battery-powered and precision measurement applications. The AD7683ARMZ includes an internal conversion clock, eliminating external timing dependencies.
Key applications include data acquisition, industrial control, medical instruments, and portable devices. Its high accuracy, low power, and small form factor make it ideal for space-constrained designs.
For detailed specifications, refer to the datasheet on Analog Devices' website.
