Overview
The ADS8361IDBQ, produced by Texas Instruments, is a dual, 16-bit, 500kSPS Analog-to-Digital (A/D) converter. This component is designed for high-speed, simultaneous signal acquisition and features four fully differential input channels grouped into two pairs. It is particularly suited for applications requiring precise and simultaneous conversion of multiple analog signals. The ADS8361 operates with an internal +2.5V reference and can also accept an external reference in the range of 1.2V to 2.6V. It is available in SSOP-24 and QFN-32 packages and is fully specified over the –40°C to +125°C operating temperature range.
