Texas Instruments ADS2806Y/250
The ADS2806 is a dual, high-speed, high dynamic range, 12-bit pipelined Analog-to-Digital Converter (ADC). This converter includes a high-bandwidth track-and-hold that gives excellent spurious performance up to and beyond the Nyquist rate. The differential nature of this track-and-hold and ADC circuitry minimizes even-order harmonics and gives excellent common-mode noise immunity. The track-and-hold can also be operated single-ended.
The ADS2806 provides for setting the full-scale range of the converter without any external reference circuitry. The internal reference can be disabled allowing low drive, external references to be used 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 to allow for multiplexing and testability on a PC board.
The ADS2806 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. The ADS2806 is available in a TQFP-64 power package.
