AD7858BNZ Analog Devices ADC 12-Bit 8-Ch 3/5V 200kSPS 1/2LSB

RS Components Part # 759-2477

Manufactured by Analog Devices - Part # AD7858BNZ - 24 Pin PDIP Package

DESCRIPTION

The AD7858 is a high-speed, low-power, 12-bit ADC that operates from a single 3 V or 5 V power supply, the AD7858 being optimized for speed. The ADC powers up with a set of default conditions at which time it can be operated as a read-only ADC. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and have a number of power-down options for low-power applications. The part powers up with a set of default conditions and can operate as a read-only ADC.
