The AD7851 is a high speed, 14-bit ADC which operate from a single 5V 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 272kHz 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 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 140 kHz.
CMOS construction ensures low power dissipation (60 mW typ) with power-down mode (5 µW typ). The part is available in 24- pin, 0.3 inch-wide dual-in-line package (DIP), 24 lead small outline (SOIC) and 24 lead small shrink outline (SSOP) packages.
