Description

The ADS7800 is a complete 12-bit sampling analog-to-digital 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.
