Single ADC SAR 285KSPS 14Bit Serial 24Pin SOIC W Tube
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.
