... VCC A3290-DS Consumer and Industrial Applications Description The A3290 and A3291 Hall effect latches are extremely temperature-stable and stress-resistant sensors, especially suited for operation over extended temperature ranges (up to 125°C). Superior high-temperature performance is made possible through Dynamic Offset Cancellation, which reduces the residual offset voltage normally caused by device package overmolding, temperature dependencies, and thermal stress ...

... Stabilized Amplifiers with a Track-and-Hold Signal Demodula- tor. +V HALL Operation The outputs of the A3290 and A3291 switch low (turn on) when a magnetic field perpendicular to the Hall sensor transitions through and exceeds the Operate Point threshold, B –V HALL illustrated in figure 3. After turn-on, the output is capable of ...
