Description

ADC 8BIT 200KSPS SOIC-8

The AD7823 is a high speed, low power, 8-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The part con- tains a 4 µs typ successive approximation A/D converter, inherent track-and-hold functionality (with a pseudo differential input) and a high speed serial interface that interfaces to most microcon- trollers. The AD7823 is fully specified over a temperature range of –40°C to +125°C. By using a technique that samples the state of the CONVST (convert start) signal at the end of a conversion, the AD7823 may be used in an automatic power-down mode. When used in this mode, the AD7823 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 AD7823 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 conver- sion time of the AD7823 is 4 µs typ. The maximum throughput rate is dependent on the speed of the serial interface of the microcontroller. The part is available in a small, 8-lead 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.
