Product Description

The AD7859ASZ is a high speed, low power 8-channel 12-bit Analog-to-digital Converter (ADC) which operates from a single 3/5V power supply, the converter being optimized for speed and the converter for low power. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and has a number of power-down options for low power applications. It is capable of 200kHz throughput rate while it is capable of 100kHz throughput rate. The input track-and-hold acquires a signal in 500ns and features a pseudo-differential sampling scheme. The converter input voltage range is 0 to VREF (uni-polar) and -VREF/2 to +VREF/2 about VREF/2 (bipolar) with both straight binary and 2s complement output coding respectively. Input signal range is to the supply and the part is capable of converting full-power signals to 100kHz. CMOS construction ensures low power dissipation of typically 5.4mW for normal operation and 3.6µW in power-down mode.
