The AD7859/AD7859L are high speed, low power, 8-channel, 12-bit ADCs which operate from a single 3 V or 5 V power supply, the AD7859 being optimized for speed and the AD7859L for low power. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and have a number of power-down options for low power applications. The AD7859 is capable of 200 kHz throughput rate while the AD7859L is capable of 100 kHz throughput rate. The input track-and-hold acquires a signal in 500 ns and features a pseudodifferential sampling scheme. The AD7859 and AD7859L input voltage range is 0 to VREF (unipolar) 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 100 kHz.
