austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analogue integrated circuits (ICs) for communication, industrial, medical and automotive applications,has expanded its A/D converter portfolio with the new AS1524 12-bit, ultra low-power single-channel full-differential A/D converter and the AS1525 dual-channel single-endedultra low power A/D converter. Combining ultra low-power operation at a high sampling speed of 150ksps with excellent dynamic performance in a small 3x3mm TDFN 8pin package, the AS1524/25family is an optimal solution for small battery-powered devices and portable data acquisition systems such as remote sensors or pen digitizers with thought space requirements.

Demonstrating austriamicrosystems' continued industry leadership in low power consumption, the AS1524/25, consumes only 350µA (3V) at the 150ksps maximum sampling rate. The advanced automatic shutdown feature places the device between conversions into sleep mode reducing the power consumption significantly at lower sampling speeds. At reduced speed of 100ksps the power consumption drops to 245µA (3V). The consumption drops down to 2.5µA at a still reasonable speed of 1ksps and stunning 200nA during shutdown.

"These A/D converters are perfect for applications with extremely demanding power consumption and space requirements. One of the key aspects of its design in terms of the reduction in power consumption, is the intelligent automatic shutdown. Thanks to this unique circuitry design the AS1524/25 is always in the perfect operating point drawing a minimum current during all sampling rates," said Walter Moshammer, marketing director for standard linear at austriamicrosystems.

SPI, QSPI and a Microwire-compatible interface enable high-speed data access while minimising board space. Both devices generate an internal clock; however, they also support an external clock for increased flexibility. 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.
