AD7622BSTZ

AD7622BSTZ Description

The AD7622BSTZ from Analog Devices Inc. is a high-performance 16-bit SAR (Successive Approximation Register) ADC designed for precision data acquisition systems. Operating at a 2MSPS sampling rate, it delivers exceptional accuracy with differential input capability, making it ideal for demanding industrial and instrumentation applications. The device supports SPI, parallel, and DSP-compatible interfaces, offering flexibility in system integration. With dual power supply rails (2.37V to 2.63V for both analog and digital), it ensures low-power operation while maintaining signal integrity. Part of the PulSAR® series, the AD7622BSTZ features an external/internal reference option and a 1:1 S/H:ADC ratio, enabling high-speed, low-latency conversions. Packaged in a 48-pin LQFP, it is RoHS3 compliant and rated for MSL 3 (168 hours) moisture sensitivity.
