Overview
The AD573JN is a 10-bit successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This integrated circuit is a complete ADC system, incorporating a digital-to-analog converter (DAC), voltage reference, clock, comparator, successive approximation register (SAR), and three-state output buffers, all fabricated on a single chip. The AD573JN operates on +5 V and –12 V to –15 V supplies and can accept analog inputs in either unipolar (0 V to +10 V) or bipolar (–5 V to +5 V) configurations. It is known for its high accuracy and reliability, with no missing codes over its entire operating temperature range.
