Overview
The AD573JD is a 10-bit successive approximation analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic IC integrates a digital-to-analog converter (DAC), voltage reference, clock, comparator, successive approximation register (SAR), and three-state output buffers on a single chip. The AD573JD is designed to operate without the need for external components to perform a full accuracy 10-bit conversion, which is completed in 20 microseconds. It utilizes advanced integrated circuit design and processing technologies, including laser trimming of the high stability SiCr thin-film resistor ladder network and a temperature-compensated subsurface Zener reference for high accuracy.
