austriamicrosystems has introduced the AS1542, a multi-channel successive-approximation ADC that features low power consumption, and excellent DC performance and dynamic specifications. The AS1542's conversion speed of 1Msps, combined with 16 input channels, makes the device suitable for optical networking, wired and wireless communications and all forms of data acquisition.
The AS1542 offers high 12-bit resolution on each of the sixteen input channels and uses advanced design techniques to achieve very low power dissipation at high throughput rates. 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.
