Honeywell HT574
The HT574 is a general purpose, 12-bit successive approximation A/D converter intended for applications with an extremely wide operating temperature range. The HT574 includes a switched capacitor, digital-to-analog converter, internal reference, comparator, successive approximation register, sample and hold, oscillator and architecture which allows it to be used with minimal external components. The HT574 provides 12-bit conversions in 10µs over the entire -55 to +225°C temperature range.| Part No. | HT574 |

GENERAL DESCRIPTION
Fabricated with Honeywell’s dielectrically isolated high temperature (HTMOS™) process, it is designed specifically for severe high-temperature applications. 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 ±5V may be selected from the internal resistor scaling network. Typically, parts will operate up to +300°C for a year, with derated performance. All parts are burned in at 250°C to eliminate infant mortality. 28-LEAD PACKAGE D C All dimensions in inches Right Reading on...
