ADI AD7851ARZ-REEL

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 ( 0V to V_REF and -V_REF/2 to +V_REF/2 centered about V_REF/2 ). Input signal range is to V_DD and the part is capable of converting full power signals to 20 MHz. CMOS construction ensures low power dissipation (<60mW typ) with power-down mode (5 μw typ). The part is available in a 24-lead, 0.3 inch-wide PDIP, a 24-lead SOIC, and a 24-lead SSOP package.
