DESCRIPTIONThe 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 inter-
nal 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 imag-
ing applications. The ADS2807 is available in a TQFP-64
power package.
