资 源 简 介
The Intersil HI-7159A is a monolithic A/D converter that usesa unique dual slope technique which allows it to resolve inputchanges as small as 1 part in 200,000 (10μV) without the useof criTIcal external components. Its digital autozeroing featurevirtually eliminates zero drift over temperature. The device isfabricated in Intersil’ proprietary low noise BiMOS process,resulTIng in excepTIonal linearity and noise performance. TheHI-7159A’s resoluTIon can be switched between a highresolution 200,000 count (51/2 digit) mode, and a high speed20,000 count (41/2 digit) mode without any hardwaremodifications. In the 41/2 digit uncompensated mode, speedsof 60 conversions per second can be achieved. The HI-7159Ais designed to be easily interfaced with most microprocessorsthrough either of its three serial and one parallel interfacemodes. In the serial modes, any one of four common baudrates is available.
