A1373 and A1374 High Precision, Output Pin Programmable Linear Hall Effect Sensors Features and Benefits ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ Output pin programming Field-programmable for optimal application integration Selectable coarse and fine gain and quiescent output voltage Selectable sensitivity temperature coefficient Selectable output clamp voltage level, including noclamp (rail-to-rail) Selectable output polarity Unipolar or bipolar operation Ratiometric sensitivity, clamps, and quiescent output voltage Chopper-stabilized Hall technique Wide operating temperature range On-chip regulator for over/under voltage protection On-chip regulator provides EMI robustness Wide lead-spacing with KB package Description The A1373 and A1374 high precision linear Hall effect sensors are sensitive, temperature stable, linear devices with externally programmable features. This device family incorporates a chopper-stabilized amplifier, voltage regulator, programming logic, and an output amplifier on a single IC. The patented dynamic offset cancellation used with a chopper-stabilization technique provides extremely low offset and minimal temperature drift. A high frequency clock is used for chopping, to ensure high frequency signal processing capability. The A1373 and A1374 are ideal for use in automotive and industrial linear position-sensing applications that require increased reliability and accuracy over conventional contacting-potentiometer solutions. Key applications include: throttle posi...
