Press Release Summary:
Available in 8-pin, 3 x 3 mm TDFN package, 10-bit AS1528/29 suit battery-powered devices and portable DAQ systems. Both AS1528 single-channel fully differential ADC and AS1529 dual-channel single-ended ADC consume less than 350 µA at max sampling rate. Automatic shutdown (sleep mode) between conversions enables lower rates of power consumption down to 2.5 µA at 1 Ksps or 200 nA during shutdown. SPI, QSPI, and Microwire-compatible interface enable high-speed data access.
Original Press Release:
austriamicrosystems Launches AS1528/29 Micro-Power, 10-bit, 150Ksps A/D Converters Offering Single-Ended and Fully-Differential Input
AS1528/29 is ideal for applications with strict low power requirements such as battery powered data acquisition systems, remote sensors or pen digitizers
Unterpremstaetten, Austria (November 12, 2007) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog ICs for communications, industrial, medical and automotive applications, has expanded its micro-power A/D converter family with the new and cost efficient AS1528 10-bit, ultra-low power single-channel fully-differential A/D converter and the AS1529 dual-channel single-ended ultra-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 AS1528/29 family is an optimal solution for small batterypowered devices and portable data acquisition systems such as remote sensors or pen digitizers with tough space requirements.
In line with the micro-power consumption of their 12-bit brothers AS1524/25, the 10-bit AS1528/29 also consume less than 350µA (3V) at the 150ksps maximum sampling rate. The advanced automatic shutdown feature places the device into sleep mode between conversions, significantly reducing power consumption at lower sampling speeds. Power consumption drops to 245µA (3V) at a reduced speed of 100ksps, further down to only 2.5µA at a still reasonable speed of 1ksps and to 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 their design in terms of power reduction is the intelligent automatic shutdown. Thanks to this unique design, the AS1528/29 is always at the perfect operating point drawing the minimum current across all sampling rates," said Walter Moshammer, marketing director Standard Linear at austriamicrosystems.
Besides the low power requirements the AS1528/29 offer outstanding DC performance of ±0.275LSB (max) for INL and DNL, as well as an ultra-low offset and gain error of ±0.25LSB combined with excellent dynamic specifications like a THD of -79.5dB.
SPI, QSPI and a Microwire-compatible interface enable high-speed data access to the AS1528/29 while minimising board space. Both devices generate an internal clock; however, they also support an external clock for increased flexibility. Both ICs operate from a 2.7 to 5.25V single supply.
The AS1528/29 family is available in an 8-pin 3x3mm TDFN package suitable for operating environments ranging from -40°C to +85°C.
