Overview
The AD573JP, produced by Analog Devices Inc., is a complete 10-bit successive approximation analog-to-digital converter (ADC). This monolithic device integrates a digital-to-analog converter (DAC), voltage reference, clock, comparator, successive approximation register (SAR), and three-state output buffers on a single chip. It operates on dual supplies of +5 V and –12 V to –15 V, allowing it to accept analog inputs in both unipolar (0 V to +10 V) and bipolar (–5 V to +5 V) ranges. The AD573JP is designed for high accuracy and reliability, with no external components required for full 10-bit conversion accuracy in 20 µs.
