AD976BRSZ

AD976BRSZ Description

The AD976BRSZ from Analog Devices Inc. is a high-performance 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for precision measurement applications. Housed in a compact 28-pin SSOP package, this ADC operates with a 100kSPS sampling rate, delivering high-resolution data conversion with single-ended input capability. It features a parallel data interface for seamless integration with microcontrollers and digital signal processors (DSPs). The device supports dual power supply operation (5V analog and digital), ensuring compatibility with standard industrial systems. With external/internal reference options, the AD976BRSZ offers flexibility in system design, while its SAR architecture ensures low latency and deterministic conversion timing.

AD976BRSZ Features
