Overview
The AD573JPZ is a 10-bit successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. 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 is designed to operate without the need for external components to perform full accuracy 10-bit conversions in 20 µs. The AD573JPZ is part of the AD573 series, which is known for its high accuracy and reliability over a wide temperature range.
