Texas Instruments ADS2806Y/1K5G4

Description
The ADS2806 is a dual, high-speed, high dynamic range, 12-bit pipelined Analog-to-Digital Converter (ADC). It features a high-bandwidth track-and-hold for 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 provides excellent common-mode noise immunity. The track-and-hold can also be operated single-ended.
The ADS2806 allows for setting the full-scale range of the converter without any external reference circuitry. The internal reference can be disabled, enabling the use of low drive, external references for improved tracking in multichannel systems.
The ADS2806 provides an over-range indicator flag to indicate an input signal that exceeds the full-scale input range of the converter. This flag can be used to reduce the gain of front end gain control circuitry. There is also an output enable pin for multiplexing and testability on a PC board.
The ADS2806 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. It is available in a TQFP-64 power package.
