Analog Devices Inc. AD7858BNZ

Description
The AD7858/AD7858L are high-speed, low-power, 12-bit ADCs that operate from a single 3 V or 5 V power supply. The AD7858 is optimized for speed, while the AD7858L is optimized for low power. The ADCs power up with a set of default conditions and can operate as read-only ADCs. They contain self-calibration and system calibration options to ensure accurate operation over time and temperature. The ADCs have several power-down options for low-power applications.
