DESCRIPTION
The ADS807 is a high-speed, high dynamic range,
12-bit pipelined Analog-to-Digital (A/D) converter. 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 A/D
converter circuitry minimizes even-order harmonics and gives
excellent common-mode noise immunity. The track-and-hold
can also be operated single-ended.
The ADS807 provides for setting the full-scale range of the
converter without any external reference circuitry. The internal
reference can be disabled allowing low drive, internal
references to be used for improved tracking in multichannel
systems.
The ADS807 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 ADS807 employs digital error correction techniques to
provide excellent differential linearity for demanding imaging
applications.
