The SENKO® SL920 programmable linear Hall effect sensor has been designed to provide a fully integrated Hall current sensor IC for use in current sensing applications running off of a dual supply voltage. The high voltage design allows up to a +/-18V bipolar supply and has a nominal output swing of +/-12V.The SL920 employs a segmented, linearly interpolated temperature compensation technology, providing greater accuracy in sensitivity and offset voltage trimming and hence virtually zero temperature drift. This improvement does not degrade the high analog signal bandwidth of the device but greatly reduces total error over the operating temperature range. The sensor incorporates a highly sensitive Hall element with a BiCMOS interface integrated circuit, a small-signal high-gain amplifier, a clamped low-impedance output stage, and a proprietary, high bandwidth dynamic offset cancellation technique. The SL920 Hall effect sensor is extremely fast and temperature stable providing an open loop Hall effect solution that can compete with more expensive closed loop devices. The sensor is available in an ultra-thin (1.6 mm thick), through-hole single in-line package (TO94)
