ADS8568SPMR

Analog To Digital Converters (ADC) Overview

The ADS8568SPMR is a Texas Instruments analog-to-digital converter featuring eight simultaneous-sampling channels with 16-bit resolution. It utilizes a Successive Approximation Register (SAR) architecture to achieve sampling rates up to 500 kS/s per channel. The device supports both parallel and serial SPI interfaces and allows daisy-chaining for multi-device systems. It operates on an analog supply voltage of 5 V and a digital supply ranging from 2.7 V to 5.5 V. The component is housed in a 64-pin LQFP package and functions within a temperature range of -40°C to +125°C.
