●Product Details
●The AD7856 is a high speed, low power, 14-bit Analog-to-Digital Converter (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 it has a number of power-down options for low power applications.
●The AD7856 is capable of 285 kHz throughput rate. The input track-and-hold acquires a signal in 500 ns and features a pseudo-differential sampling scheme. The AD7856 voltage range is 0 to VREF with both straight binary and 2s complement output coding. Input signal range is to the supply and the part is capable of converting full power signals to 20 MHz.
●CMOS construction ensures low power dissipation of typically 5.4 mW for normal operation and 3.6 µW in power-down mode. 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.
