Overview
The ADS8361IDBQR is a dual, 16-bit, 500kSPS analog-to-digital converter (ADC) produced by Texas Instruments. This device features four fully differential input channels grouped into two pairs, enabling high-speed, simultaneous sampling. It operates from a +3V/+5V supply and includes dual successive approximation ADCs, two differential sample-and-hold amplifiers, and an internal +2.5V reference. The ADS8361IDBQR is designed for applications requiring precise and simultaneous conversion of multiple analog signals.
