GENERAL DESCRIPTION

The HT574 is a general purpose, 12-bit successive approxi-

mation A/D converter intended for applications with an

extremely wide operating temperature range. Fabricated

with Honeywell鈥檚 dielectrically isolated high temperature

(HTMOS鈩? process, it is designed specifically for severe

high-temperature applications.

The HT574 includes a switched capacitor, digital-to-analog

converter, internal reference, comparator, successive ap-

proximation register, sample and hold, oscillator and archi-

tecture which allows it to be used with minimal external

components. Tristate output buffers and digital control pins

are also provided for microprocessor interfacing. Analog

input signal ranges of 0 to +10V, 0 to +20V, or

鹵5V

may be

selected from the internal resistor scaling network.

The HT574 provides 12-bit conversions in 10碌s over the

entire -55 to +225擄C temperature range. Typically, parts will

operate up to +300擄C for a year, with derated performance.

All parts are burned in at 250擄C to eliminate infant mortality.
