With pulse width modulation, double wire output
Worcester, Massachusetts- 亚博棋牌游戏Allegro MicroSystems introduced a new linear hall effect sensor IC, the IC has a wider temperature range (40 ℃ to 150 ℃).Allegro companyA1357Device is high precision programmable linear hall effect IC customers, with pulse width modulation (PWM) and power output (double).PWM output signals (frequency: 1 kHz) duty ratio (DC) and is proportional to the applied magnetic field.This device can through its built-in hall sensor component converts analog signals to digital coding of the PWM output signal.Digital coding of the PWM output coupling noise resistance is far better than the analog output signal noise resistance.
A1357 with BiCMOS monolithic circuit, the circuit integrated hall element, is used to reduce the inherent sensitivity of hall element and offset drift of high-precision temperature compensation circuit, small signal dynamic offset cancellation circuit, high gain amplifier, proprietary and PWM switching circuit.Dynamic offset cancellation circuit can reduce the residual offset voltage of the hall element.Hall element migration is usually a moulded device, temperature dependence and the thermal stress caused by.High frequency offset cancellation (chopped) clock can support higher sampling rate, so as to improve the accuracy of output signal, to achieve faster signal processing ability.
A1357 sensor IC is dedicated to automotive and industrial market, adopt single into 3 pin type lead-free packaging, fog and with 100% of tin plating pin frame.
