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.
