TL173L, TL173C LINEAR HALL-EFFECT SENSORS

• Output Voltage Linear with Applied Magnetic Field
• Sensitivity Constant Over Wide Operating Temperature Range
• Solid-State Technology
• Three-Terminal Device
• Senses Static or Dynamic Magnetic Fields

The TL173L and TL173C are low-cost magnetic field sensors designed to provide a linear output voltage proportional to the magnetic field they sense. These monolothic circuits incorporate a Hall element as the primary sensor along with a voltage reference and a precision amplifier. Temperature stabilization and internal trimming circuitry yield a device that features high overall sensitivity accuracy with less then 5% error over its operating temperature range.

The TL173L is characterized for operation from -20°C to 85°C. The TL173C is characterized for operation from 0°C to 70°C.

1. Voltage values are with respect to network ground terminal.
2. For operation above 25°C free-air temperature, aerate linearly at the rate of 6.2 mW/°C

The circuits in Figure 3 may be used to set the output voltage at zero field strenght to exactly 6V (using R1), and to set the sensitivity to exactly -15 V/T (using R2), as depicted in Figure 4.
