Overview
The ADS2807Y/1K5G4 is a dual, high-speed, 12-bit pipelined Analog-to-Digital Converter (ADC) produced by Texas Instruments. This converter is designed for high dynamic range applications and features a high-bandwidth track-and-hold circuit that provides excellent spurious performance up to and beyond the Nyquist rate. The differential nature of the track-and-hold and ADC circuitry minimizes even-order harmonics and offers excellent common-mode noise immunity. The ADS2807Y/1K5G4 is available in a TQFP-64 power package and is suitable for demanding imaging and other high-speed data acquisition applications.
