Each device includes two individually programmable reference sources that can be used for system-level gain calibration. Also, a flexible serial interface that can operate over a wide power-supply range enables easy munication with a large variety of host controllers. Power consumption for a given throughput can be optimized by using the two lowpower modes supported by the device. All devices are fully specified over the extended industrial temperature range (- 40°C to 125°C) and are available in pin-patible, WQFN-16 (3-mm × 3-mm) and TSSOP-16 packages. Device...
