ADS8668IDBT

Analog To Digital Converters (ADC) Overview

The ADS8668IDBT is an eight-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a single-ended input configuration and supports a sampling rate of 500 kSPS. The device utilizes a standard SPI digital interface for data communication. It requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 1.65 V and 5.25 V. The component is housed in a 38-pin TSSOP package and functions within a temperature range of -40°C to +125°C.
