AD7823YRZ Datasheet PDF - ADI

●The AD7823YRZ is a high speed low power 8-bit Analog-to-digital Converter (ADC) that operates from a single 2.7 to 5.5V supply. The part contains a 4µs typical successive approximation A/D converter, inherent track-and-hold functionality and a high speed serial interface that interfaces to most microcontrollers. By using a technique that samples the state of the CONVST signal at the end of a conversion, the converter may be used in an automatic power-down mode. When used in this mode, the converter powers down automatically at the end of a conversion and wakes up at the start of a new conversion. This feature significantly reduces the power consumption of the part at lower throughput rates. The converter can also operate in a high speed mode where the part is not powered down between conversions. In this high speed mode of operation, the conversion time of the converter is 4µs typical. The maximum throughput rate is dependent on the speed of the serial interface of the microcontroller.
