austriamicrosystems expands AD converter family with new 8-channel fully differential 12-bit A/D converter with 200ksps sampling speed

austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog integrated circuits (ICs) for communication, industrial, medical and automotive applications, has expanded its high-performance ADC portfolio with the introduction of the AS1534 – a parallel interface A/D converter with extremely low power consumption. Combining high speed and low power consumption with outstanding dynamic performance (THD < -78dB), the AS1534 A/D converter is the ideal solution for battery-powered devices and portable data acquisition systems such as remote sensors or pen digitizers.

"The analog inputs are software configurable. Design engineers can choose either the 8-channel single-ended mode or the fully differential 4-channel mode, which offers them the utmost in flexibility for various applications. The fully differential input mode enables exceptionally precise measurements under noisy conditions, particularly those that are commonly found in industrial environments," said Walter Moshammer marketing director for standard linear at austriamicrosystems.

The AS1534 offers a 12-bit resolution on each of the eight input channels. With a conversion speed of 200ksps, while using less as 2.5mA supply current (including the internal reference), the AS1534 achieves a 36% reduction of power consumption over its nearest competitor – once again demonstrating austriamicrosystems' continued leadership in low power consumption. With a number of power-down options the power consumption can be reduced even further (0.5mA at 10ksps), and in shutdown mode the supply current drops to a stunning 1µA.

"This type of multi-input A/D converter is ideal for applications where many system parameters must be measured – and the need for such applications is increasing rapidly," added Moshammer. "With its emphasis on significant reduction in power consumption, the AS1534 is the product of choice."

The AS1534 also features an integrated 2.5V reference which reduces external component count. The AS1534 is available in a Pb-free 44-pin PQFP package suitable for operating environments ranging from -40°C to +85°C.
