ANALOG DEVICES AD573 handbook3
The AD573 is a 10-bit successive approximation analog-to-digital converter that includes a DAC, voltage reference, clock, comparator, successive approximation register (SAR) and three-state output buffers, all fabricated on a single chip. No external components are required to perform a full accuracy 10-bit conversion in 20 µs. The AD573 incorporates advanced integrated circuit design and processing technologies. The successive approximation technique is used to implement the conversion, which is a digital conversion technique in which the input signal is compared with the reference voltage at each conversion. The result of the comparison is the most significant bit that is discarded, and the other bits are used to calculate the next reference voltage.

Questions answered in these manuals
How is a conversion started on the AD573?
A positive CONVERT pulse at least 500 ns wide initiates the conversion cycle.
What package options are available for the AD573?
The AD573 is offered in 20‑pin ceramic DIP, 20‑pin plastic DIP, and 20‑pin leaded chip carrier packages.
How can the AD573 be configured for unipolar and bipolar input ranges?
For unipolar operation (0 V to +10 V) short the bipolar offset control pin to digital common; for bipolar operation (–5 V to +5 V) leave the offset pin open.
What is the maximum conversion time of the AD573?
Conversion time ranges from 10 µs to 30 µs depending on the device version, with 10 µs typical for the fastest version.
