Hot-selling and scarce AD7856KRZ 5 V Single Supply, 8-Channel 14-Bit 285 kSPS Sampling ADC SOP24 spot stock

Product Descriptions

The AD7856 is a high speed, low power, 14-bit ADC that operates from a single 5 V power supply . The ADC powers up witha set of default conditions at which time it can be operated as aread only ADC . The ADC contains self-calibration and systemcalibration options to ensure accurate operation over time andtemperature and it has a number of power-down options for lowpower applications .

The AD7856 is capable of 285 kHz throughput rate .  The inputtrack-and-hold acquires a signal in 500 ns and features a pseudodifferential sampling scheme . The AD7856 voltage range is 0 toV_REF with straight binary output coding . Input signal range is tothe supply and the part is capable of converting full power signals to 10 MHz .

CMOS construction ensures low power dissipation of typically60 mW for normal operation and 5.1 mW in power-down modeat 10 kSPS throughput rate . The part is available in 24-lead,0.3 inch-wide dual in-line package (DIP), 24-lead small outline(SOIC) and 24-lead small shrink outline (SSOP) packages .Please see page 31 for data sheet index .
