ANALOG DEVICES  AD7851ARSZ  模数转换器, 14 bit, 333 kSPS, 单, 4.75 V, 5.25 V, SSOP

Product Details

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.
