A1360, A1361, and A1362 Low-Noise Programmable Linear Hall Effect Sensor ICs with Adjustable Bandwidth (50 kHz Maximum) and Analog Output Features and Benefits • mm case thickness provides greater coupling for current 1 sensing applications • Customer programmable offset and sensitivity • Factory programmed 0% / °C sensitivity temperature coefficient • Programmability at end-of-line • Selectable unipolar or bipolar quiescent voltage levels • Selectable sensitivity ranges between 0.7 and 1.4 mV/G (A1360), 1.4 to 4.5 mV/G (A1361) and 4.5 to 16 mV/G (A1362) • Device bandwidth selectable under 50 kHz, via capacitor on FILTER pin • Ratiometric sensitivity, quiescent voltage output, and clamps for interfacing with application DAC • Temperature-stable quiescent voltage output and sensitivity • Precise recoverability after temperature cycling • Output voltage clamps provide short circuit diagnostic capabilities • Wide ambient temperature range: – 40°C to 150°C • Resistant to mechanical stress 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). Package: 4 pin SIP (suffix KT) 1 mm case thickness 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.
