Overview
The AD571KD/+ from Analog Devices Inc. is a complete 10-bit successive approximation analog-to-digital converter (ADC). This device is designed to provide a full analog-to-digital conversion function without the need for external components. It operates using a +5 V and –15 V power supply, although the AD571K version can also operate with up to a +15 V supply, enabling direct interface with CMOS logic.
