austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of analog ICs for communications, industrial, medical and automotive applications, has introduced the AS1542, a multi-channel successive-approximation ADC with lowest power consumption, excellent DC performance and outstanding dynamic specifications, expanding austriamicrosystems high-performance ADC portfolio. The high speed of 1Msps combined with 16 input channels makes the AS1542 ideal for networking equipment, motor control, industrial automation, 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. At a conversion speed of 1Msps the AS1542 uses as less as 2.4mA, while in automatic shutdown mode the supply current drops to less than 0.5uA.
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.
"There is an escalating demand for increased channel count on analog-to-digital converters and the AS1542 helps meet that requirement with 16 channels. Typical applications needing more channels include optical, wired and wireless communications, motor control, industrial automation and all forms of data acquisition," said Walter Moshammer, Marketing Director Standard Linear at austriamicrosystems. “At the same time, the fully differential input mode of the AS1542 enables very precise measurements under noisy conditions often found in industrial environments.”
This 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. Product-specific information and free samples via austriamicrosystems’ online shop ICdirect are available at http://www.austriamicrosystems.com/AS1542/description_AS1542.htm
