General Description

The ALD521D is a digital controller designed to interface to the ALD500 or ALD500R integrating dual slope analog processors as a chip set for building a precision analog-to-digital converter.

With the ALD521D and ALD500R, together with a few external capacitors and resistors, a precision Analog to Digital converter with auto zero and auto-polarity can be implemented.

The ALD521D can operate in either a stand-alone mode or in an external microprocessor control mode.
