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.
T he AD7851 is capable of 333 kHz throughput rate. T he input
track-and-hold acquires a signal in 0.33
μ
s 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
DD
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
μ
W 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.
