Overview

SS490 Series Hall-effect linear sensor IC, 3.00 min., 3.125 typ., 3.25 max. mV/G sensitivity, flat TO-92-style, straight long leads, 1000 units/bag.

The SS490 Series are small, versatile, linear Hall-effect devices which are operated by the magnetic field from a permanent magnet or an electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field.

The integrated circuitry provides increased temperature stability and sensitivity. Laser-trimmed, thin film resistors provide high accuracy (null to ±%, sensitivity up to ±3%) and temperature compensation. They respond to either positive or negative Gauss, monitoring either or both magnetic poles. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The positive temperature coefficient of the sensitivity (+0.02%/°C typical) helps compensate for the negative temperature coefficients of low-cost magnets, providing a robust design over a wide temperature range. Rail-to-rail operation (over full voltage range) provides a more usable signal for higher accuracy. These products have an operating temperature range of -40°C to 150°C [-40°F to 302°F], appropriate for industrial and automotive environments.

The SS490B versions offer cost-effective sensing solutions with wider null and sensitivity tolerances, and a wider drift over temperature than the SS490A higher performance products. Both the SS490A and SS490B versions have a typical sinking or sourcing output of 1.5 mA continuous, use 7 mA supply current at 5.0 V at 25°C [77°F], and provide predictable performance over the full temperature range.

For design flexibility, these products are available in the following flat TO-92 package styles:
  • SS4XX: Straight standard leads, bulk pack
