DESCRIPTION

The ADS2806 is a dual, high-speed, high dynamic range,

12-bit pipelined Analog-to-Digital Converter (ADC). This con-

verter 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 excel-

lent common-mode noise immunity. The track-and-hold can

also be operated single-ended.

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 imag-

ing applications. The ADS2806 is available in a TQFP-64

power package.

The ADS2806 provides for setting the full-scale range of the

converter without any external reference circuitry. The internal
