T he AD7851 is a high speed, 14-bit ADC that operates from a

single 5 V power supply. T he ADC powers-up with a set of

default conditions at which time it can be operated as a read-

only ADC. T he 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.

1. Single 5 V supply.

2. Operates with reference voltages from 4 V to V_DD

3. Analog input ranges from 0 V to V_DD

4. System and self-calibration including power-down mode.

5. Versatile serial I/O port.

T he AD7851 is capable of 333 kHz throughput rate. T he input

track-and-hold acquires a signal in 0.33 µs and features a

pseudo-differential sampling scheme. T he AD7851 has the

added advantage of two input voltage ranges (0 V to V_REF,and

–V_REF/2 to +V_REF/2 centered about V_REF/2). Input signal range

is to V_DDand the part is capable of converting full-power signals

to 20 MHz.

CMOS construction ensures low power dissipation (60 mW typ)

with power-down mode (5 µW typ). T he 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.
