TSSOP-20 4-channel 24-bit DAC provides 240 samples/s

December 2004
Portable Design;Dec2004, Vol. 10 Issue 12, p35
The article presents information on the ADS 1224 four-channel 24-bit delta-sigma ADC. It provides a 240-sample/s data rate and is designed for high-resolution measurement applications where space and power consumption are critical, such as portable instrumentation, portable medical equipment, industrial process control, remote sensors and smart transmitters. The converter includes a four-channel differential input multiplexer, which accepts rail-to-rail inputs and features a temperature sensor for ambient temperature measurement. The ADC quickly shuts down (standby mode) while idle between measurements to dramatically reduce overall power consumption.
