The AD7851 is a high speed, 14-bit ADC that operates from a
single 5 V power supply. The ADC powers up with a set of default
conditions at which time it can be operated as a read-only ADC.
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.
The AD7851 is capable of a 333 kHz throughput rate. The
input track-and-hold acquires a signal in 0.33 μs and features
a pseudo-differential sampling scheme. The AD7851 has the
added advantage of two input voltage ranges (0 V to VREF and
–VREF/2 to +VREF/2 centered about VREF/2). Input signal
range is to VDD and the part is capable of converting full
power signals to 20 MHz.
