ADS7800
DESCRIPTION
The ADS7800 is a complete 12-bit sampling analog-
to-digital converter using state-of-the-art CMOS struc-
tures. It contains a complete 12-bit successive ap-
proximation A/D converter with internal sample/hold,
reference, clock, digital interface for microprocessor
control, and three-state output drivers.
The ADS7800 is specified at a 333kHz sampling rate.
Conversion time is factory set for 2.70
μ
s max over
temperature, and the high speed sampling input stage
insures a total acquisition and conversion time of 3
μ
s
max over temperature. Precision, laser-trimmed scal-
ing resistors provide industry-standard input ranges of
±
5V or
±
10V.
AC and DC performance are completely specified.
Two grades based on linearity and dynamic perform-
ance are available to provide the optimum price/
performance fit in a wide range of applications.
The 24-pin ADS7800 is available in plastic and side-
braze hermetic 0.3" wide DIPs, and in an SOIC
package. It operates from a +5V supply and either a
–12V or –15V supply. The ADS7800 is available in
grades specified over 0
°
C to +70
°
C and –40
°
C to
+85
°
C temperature ranges.
