Overview
The ADS8361IDBQRG4, 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 sampling of multiple analog signals.
The ADS8361 offers low power consumption of 150mW, an internal 2.5V reference, and a flexible serial interface. It is available in SSOP-24 and QFN-32 (5x5) packages and is fully specified over an operating temperature range of –40°C to +125°C.
