GENERAL DESCRIPTION
The AD7851 is a high speed, 14-bit 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 has a
number of power-down options for low power applications.
The AD7851 is capable of a 333 kHz throughput rate. The
input track-and-hold acquires a signal in 0.33
s and features
a pseudo-differential sampling scheme. The AD7851 has the
added advantage of two input voltage ranges (0 V 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 20 MHz.
CMOS construction ensures low power dissipation (60 mW typ)
with power-down mode (5
W typ). The part is available in a
24-lead, 0.3 inch-wide PDIP, a 24-lead SOIC, and a 24-lead
SSOP package.
PRODUCT HIGHLIGHTS
1. Single 5 V supply.
2. Operates with reference voltages from 4 V to VDD.
3. Analog input ranges from 0 V to VDD.
4. System and self-calibration including power-down mode.
5. Versatile serial I/O port.
