austriamicrosystems Launches Dual, Simultaneous Sampling 1MSPS ADC

(Product News, 8 May 2008)

austriamicrosystems has released AS1545, a dual high-speed successive-approximation ADC that offers 12-bit resolution on each of the two ADCs and uses advanced design techniques to achieve low power dissipation at high throughput rates. At a conversion speed of 1MSPS and including the internal 2.5V reference, the AS1545 uses only 5.5mA. In full power-down mode the supply current drops to less than 1µA.

Two complete and independent ADC channels allow simultaneous sampling and conversion of two channels. The 12 input channels are software configurable allowing each ADC to offer six single-ended channels or three fully or pseudo differential pairs, as programmed. The conversion result of both ADCs is simultaneously available on separate data lines or in succession on one data line if only one serial port is available.

The device operates from a single 2.7V to 5.25V supply and contains a Vdrive (interface drive voltage) function which enables the serial interface to connect directly to either 3V or 5V processor systems independent of the ADC's supply voltage. The ADC can be interfaced via a high speed SPI/QSPI/Microwire or DSP interface.
