The ADS2807 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 ADS2807 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 ADS2807 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 ADS2807 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. The ADS2807 is available in a TQFP-64 power package.
