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 for setting the full-scale range of the
converter without any external reference circuitry. The internal

reference can be disabled allowing low drive, external refer-
ences 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 imag-
ing applications. The ADS2806 is available in a TQFP-64
power package.
