Austriamicrosystems has expanded its A/D converter portfolio with the AS1524 12-bit, low-power single-channel full-differential A/D converter and the AS1525 dual-channel single-ended A/D converter. The AS1524/25, consumes 350µA (3V) at the 150ksps maximum sampling rate. At reduced speed of 100ksps the power consumption drops to 245µA (3V). The consumption drops down to 2.5µA at a speed of 1ksps and 200nA during shutdown.

Both devices generate an internal clock; however, they also support an external clock. Both parts operate from a 2.7 to 5.25V single supply. The AS1524/25 family is available in an 8-pin 3x3mm TDFN package suitable for operating environments ranging from -40°C to +85°C.
