SP1674B General Description

The SP574B/674B/1674B/774B (SPx74B) Series are complete 12bit successiveapproximation A/D converters integrated on a single die with tri-state output latches, an internal reference, clock and a samplehold. The new "BSeries" features true Nyquist sampling while maintaining compatibility with prior versions. They are dropin replacements for the older 574A/674A/1674A/774A type devices.

SP1674B Features

The SPx74B Series feature standard bipolar and unipolar input ranges of 10V and 20V. Input ranges are controlled by a bipolar offset pin and laser-trimmed for specified linearity, gain and offset accuracy. Power requirements are +5V and +12V to +15V with a maximum dissipation of 150mW at the specified voltages. Conversion times of 8s, 10s, 15s and 25ms are available,as are units with 10, 25 or 50ppm/°C temperature coefficients for flexible matching to specific application requirements.

The SPx74B Series are available in nine product grades for each conversion time. The J and K models are specified over 0°C to +70°C commercial temperature range; the A and B models are specified over the 40°C to +85°C industrial temperature range; the S and T models are specified over the 55°C to +125°C military temperature range. Package options include 28pin CDIP, 28pin plastic DIP (both narrow and wide), 28-pin PLCC and 28pin SOIC.
