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.

DESCRIPTION

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 employs digital error correction techniques to

provide excellent differential linearity for demanding imag-

ing applications. The ADS2807 is available in a TQFP-64

power package.

The ADS2807 provides for setting the full-scale range of the

converter without any external reference circuitry. The inter-

nal reference can be disabled allowing low-drive, external

references to be used for improved tracking in multichannel

systems.
