Convertor provides high
resolution at low power
The latest 24bit delta-sigma analogue-to-digital convertor from Texas Instruments combines low power consumption of 90uA with the miniature size of an MSOP-10 package
This easy-to-use ADC is ideal for high-resolution measurements where performance, space and power consumption are critical, such as handheld instrumentation, portable medical equipment, industrial process control and weigh scales. The ADS1244 consists of a third-order delta-sigma modulator and digital filter.

Webcast to address wireless power optimisation

The analogue modulator has a +/-5V differential input stage.
The digital filter rejects both 50 and 60Hz signals, completely settles in one cycle and outputs data at 15 samples per second.
'By combining high resolution, low power, simplicity-of-use and small size, the ADS1244 provides an unequalled price/performance value for space-constrained measurement applications', said Jim Todsen, Product Manager for TI's data acquisition products.
The ADS1244 is designed to easily connect to microcontrollers, such as TI's MSP430 family of ultra-low-power microcontrollers, to offer a complete data acquisition solution.
Multiple ADS1244s can be connected together to create a synchronously sampling multichannel measurement system.
A simple two-wire serial interface provides all the necessary control.
Data retrieval, self-calibration and sleep mode are handled with a few simple waveforms.
When only single conversions are needed, the sleep mode can be used to shut down the ADS1244 when idle between measurements - dramatically reducing overall power consumption.
Power is typically less than 270uW in normal operation and less than 1uW in sleep mode.
The ADS1244 supports 2.5 to 5.25V analogue supplies and 1.8 to 3.6V digital supplies.
The ADS1244 comes in an MSOP-10 package, and is available now from TI and its authorised distributors.
Suggested resale pricing is $2.95 in 1000-piece quantities.
