New applications for linear output Hall-effect sensing, such as current measurement, require both high accuracy and increased sensor bandwidth. The Allegro A1360, A1361, and A1362 programmable linear Hall effect sensor ICs are designed specifically to achieve both goals. Available in a through-hole SIP (single in-line package), the A136x Hall effect sensor ICs are sensitive and temperature-stable. The accuracy of these devices is enhanced via programmability on the device VOUT pin. A capacitor to ground on the FILTER pin on the A136x can be used to tune the device bandwidth in a range less than 50 kHz.
These ratiometric Hall effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. The quiescent output voltage is user-adjustable around either 50% (bidirectional configuration) or 10% (unidirectional configuration) of the supply voltage, VCC. The device sensitivity is adjustable within three guaranteed ranges: 0.7 to 1.4 mV/G (A1360), 1.4 to 4.5 mV/G (A1361), and 4.5 to 16 mV/G (A1362).
Each BiCMOS monolithic circuit integrates a Hall element, temperature-compensation circuitry to reduce the intrinsic sensitivity drift of the Hall element, a small-signal high-gain amplifier, a clamped low-impedance output stage, and a proprietary dynamic offset cancellation technique.
The features of these linear Hall effect sensor ICs make them ideal for meeting high accuracy requirements in automotive and industrial applications. Device specifications are guaranteed over an extended ambient temperature range: –40°C to 150°C.
