What is UGN3187?

This is HALL-EFFECT LATCHES FOR HIGH-TEMPERATURE OPERATION.

An operational amplifier (op-amp) is an electronic device that amplifies an input signal and produces an output that is much larger than the input signal. It is commonly used in analog circuits, such as filters, oscillators, and amplifiers. The input terminals are designed to accept both positive and negative signals, which allows the op-amp to amplify both AC and DC signals.

Datasheet Summary in PDF File

3185 THRU 3189 HALL EFFECT LATCHES FOR HIGH TEMPERATURE OPERATION These Hall effect latches are extremely temperature stable and stressresistant sensors especially suited for operation over extended temperature ranges to 150 C Superior high temperature performance is made possible through a novel Schmitt trigger circuit that maintains operate and release point symmetry by compensating for temperature changes in the Hall element Additionally internal compensation provides magnetic switch points that become more sensitive with temperature hence offsetting the usual degradation of the magnetic field with temperature The symmetry capability makes these devices ideal for use in pulse counting applications where duty cycle is an important parameter The four basic devices 3185 3187 3188 and 3189 are identical except for magnetic switch points Each device includes on a single silicon chip a voltage regulator quadratic Hall voltage generator temperature compensation circuit signal amplifier Schmitt trigger and a buffered open collector output to sink up to 25 mA The on board regulator permits operation with supply voltages of 3 8 to 24 volts The first character of the part number suffix determines the device operating temperature range Suffix
