It has good temperature stability and operates over a temperature range of -40°C to 85°C with latch function.The AH3664 Hall-effect sensor includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and push–pull output driver, etc. The AH3664, produced with CMOS technology, is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.
