DESCRIPTIONThe ADS7800 is a complete 12-bit sampling analog-to-
digital (A/D) converter using state-of-the-art CMOS
structures. It contains a complete 12-bit successive
approximation 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 2.70μs max over
temperature, and the high-speed sampling input stage
insures a total acquisition and conversion time of 3μs
max over temperature. Precision, laser-trimmed scaling
resistors provide industry-standard input ranges of ±5V
or ±10V.
AC and DC performance are completely specified. Two
grades based on linearity and dynamic performance 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.
