DESCRIPTION
The ADS5232 is a dual, high-speed, high dynamic
range, 12-bit pipelined analog-to-digital converter
(ADC). This converter includes a high-bandwidth
sample-and-hold amplifier that gives excellent spurious performance up to and beyond the Nyquist
rate. The differential nature of the sample-and-hold
amplifier and ADC circuitry minimizes even-order
harmonics and gives excellent common-mode noise
immunity.
The ADS5232 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 references to be used for
improved tracking in multichannel systems.
The ADS5232 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 testing on a PC board.
The ADS5232 employs digital error correction
techniques to provide excellent differential linearity for
demanding imaging applications. The ADS5232 is
available in a TQFP-64 package.
