AD7810YRZ

AD7810 is a high-speed, low-power, 10bit A/D converter that operates from a single 2.7V to 5.5V supply. The part contains a 2.3µs successive approximation A/D converter, with inherent track/hold functionality, a pseudo-differential input, and a high-speed serial interface that interfaces to most microcontrollers. By using a technique that samples the state of the CONVST active high (convert start) signal at the end of a conversion, this may be used in an automatic power-down mode. When used in this mode, it automatically powers down 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. Applications include low-power, hand-held, portable applications that require analogue-to-digital conversion with 10bit accuracy, e.g., battery-powered test equipment, and battery-powered communications systems.
