AD7853ARSZ-REEL7

Analog To Digital Converters (ADC) Overview

The AD7853ARSZ-REEL7 is a 12-bit, single-channel Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It utilizes a Successive Approximation Register (SAR) architecture and operates from a single 3 V to 5.5 V supply. The device supports a throughput rate of 200 kSPS with a typical power dissipation of 12 mW at 3 V. It features a pseudo-differential input range of 0 V to VREF and includes system and self-calibration capabilities. The component communicates via a flexible serial interface compatible with SPI/QSPI/8051/microprocessor standards and is housed in a 24-lead SSOP package.
