Press Release Summary:
Suited for battery-powered devices and portable DAQ systems, 10-bit, single-channel AS1526/27 series combine sampling speed up to 73 kS/sec with internal clock and external clock support in SOIC-8 package. SPI-, QSPI-, and Microwire-compatible interface enables high-speed data access and minimizes board space requirements. While AS1526 features internal 2.5 V reference and consumes 4 mW, AS1527 requires external reference and consumes 3 mW. Both operate from 2.7-5.25 V supply.
Original Press Release:
austriamicrosystems Expands ADC Product Line with AS1526/27 10-bit, 73ksps, Ultra Low-Power A/D Converter Family
Ideal for battery-powered devices and portable data acquisition systems, including remote sensors or pen digitizers with strict low power requirements
Unterpremstaetten, Austria (November 14, 2006) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog integrated circuits (ICs) for communication, industrial, medical and automotive applications, has expanded its A/D converter portfolio with the new AS1526/27 family of 10-bit, singlechannel, ultra low power A/D converters. Combining ultra low-power operation at a high sampling speed of 73ksps with excellent dynamic performance in a small SOIC-8 package, the AS1526/27 family is ideal for batterypowered devices and portable data acquisition systems such as remote sensors or pen digitizers.
Demonstrating austriamicrosystems' continued industry leadership in low power consumption the AS1526, which features an internal 2.5V reference, consumes only 4mW (3V). On the other hand the AS1527, which requires an external reference, needs even less - 3mW (3V) at the 73ksps maximum sampling rate. Both parts operate from a 2.7 to 5.25V single supply.
Software power-down further reduces current consumption to 0.3µA in shutdown mode. This decreases total power consumption to a stunning 22µA at sampling rates of 1ksps (AS1527).
"This type of A/D converter is ideal for applications with demanding power consumption and space requirements, and a high conversion speed can still be achieved," said Walter Moshammer, marketing director for standard linear at austriamicrosystems.
SPI, QSPI and a Microwire-compatible interface enable high-speed data access while minimizing board space, while an integrated 2.5V reference reduces external component count. Both devices contain an internal clock - however, they also support an external clock for increased flexibility.
The AS1526/27 family is available in an 8-pin SOIC package, suitable for operating environments ranging from -40°C to +85°C.
