Low power 12-bit ADC offers fast sampling

20 February 2008 Analogue, Mixed Signal, LSI

austriamicrosystems has introduced the AS1542, a multichannel successive-approximation ADC (analog-to-digital converter) with low power consumption, excellent DC performance and dynamic specifications, expanding austriamicrosystems' high-performance ADC portfolio. The high speed of 1 MSps combined with 16 input channels makes the AS1542 suitable for networking equipment, motor control, industrial automation, wired and wireless communications and all forms of data acquisition.

The AS1542 offers 12-bit resolution on each of the 16 input channels and uses advanced design techniques to achieve very low power dissipation at high throughput rates. At a conversion speed of 1 MSps it uses as little as 2,4 mA, while in automatic shutdown mode the supply current drops to less than 0,5 μA.

The 16 input channels are software configurable as 16-channel single-ended or 8-channel fully-differential analog inputs. Additionally, a sequencer and channel counter allows continuous or single conversions on selected channels without further user input and interruption of conversions while reprogramming the ADC. This allows the channel selection function to be altered while the sequence is in progress.

The AS1542 operates from a single 2,7 to 5,25 V supply and contains a Vdrive (interface drive voltage) function which enables the serial interface to connect directly to either 3 or 5 V processor systems independent of the ADC's supply voltage. The ADC can be interfaced via a high speed SPI/QSPI/Microwire or DSP interface.

The AS1542 is available in a 28-pin TSSOP package suitable for operating environments ranging from -40°C to +85°C.
