Available in a six-lead SOT 23 package, the AD7680 16-bit successive approximation register (SAR) a/d converter provides a throughput rate of 100 ksamples/s. Using what is said to be an advanced design technique, power dissipation is 3 mW at 3V and 15 mW at 5V typical. Power consumption in shutdown mode is 0.5 µA maximum. The device operates from a single 3V to 5.25V supply and integrates a track-and-hold amplifier that guarantees performance with inputs up to 10 kHz. Data acquisition and conversion are controlled via a chip-select pin and an external serial clock. Operating temperature range is -40_C to +85_C. Price is $6.00 each/1,000.
