概述
Description
The AD7683BRMZRL7 is a 16-bit, 250 kSPS, successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates on a single 2.5V to 5.5V supply, consuming low power (1.5mW at 5V, 250 kSPS). Key features include:
- Resolution: 16-bit
- Throughput: 250 kSPS
- Input Range: 0V to VREF (externally set, up to VDD)
- Interface: SPI-compatible (3-/4-wire)
- Package: 10-lead MSOP (RL7 denotes tape-and-reel packaging)
Ideal for battery-powered, industrial, and precision measurement applications, it offers excellent linearity (±1 LSB INL) and low noise. The ADC includes a power-down mode (0.1µA typical) for energy efficiency. A built-in reference buffer simplifies design, though an external reference can also be used.
Applications: Data acquisition, medical instruments, and portable devices.
For detailed specs, refer to the datasheet.
