Analog / digital converter (ADC) National Semiconductor
National's Powerwise Analog-to-Digital Converters (ADCs) are the lowest power family of A/D converters on the market. In addition to providing extremely low power consumption over a range of sample rates, each ADC has a very efficient power down feature. For example, a single channel 1Msps PowerWise ADC used in a 10 Ksps application has a typical power consumption of 0.02 mW at 3V.
