ADS8168IRHBR

Analog To Digital Converters (ADC) Overview

The ADS8168IRHBR is a high-speed, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It integrates an 8-channel multiplexer with a track-and-hold amplifier and a 1-MSPS ADC core within a single device. The component operates with an analog supply voltage range of 3 V to 5.5 V and a digital supply range of 1.65 V to 5.5 V. It features an internal oscillator and supports both external and internal reference configurations. The device utilizes a standard SPI interface for data communication and is housed in a 32-pin VFQFN package with dimensions of 5 mm x 5 mm.
