By using a technique that samples the state of the CONVST (convert start) signal at the end of a conversion, the AD7810YRM-REEL7 may be used in an automatic power-down mode. When used in this mode, the AD7810YRM-REEL7 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. The AD7810YRM-REEL7 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 AD7810YRM-REEL7 is 2 µs. The maximum throughput rate is dependent on the speed of the serial interface of the microcontroller.
The part is available in a small 8-pin, 0.3" wide, plastic dual-in-line package (mini-DIP); in an 8-lead, small outline IC (SOIC); and in an 8-lead microSOIC package.
