The ACS764 fully integrated Hall-effect current sensor IC is designed for applications that require digital current sensing and reporting through an I2C™ bus. Allegro factory programming of the offset ...

Six automotive current sensors designed to enhance electric and hybrid vehicle performance, efficiency, and functional safety ...

Most of the Allegro unidirectional current sensor ICs are trimmed such that the zero ampere output is at 0.1 × VCC. This application note documents a simple operational amplifier circuit which can be ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

What’s the difference between a transmitter and a sensor? Nine different types of sensor transmitters. How does each type of transmitter work? What are the components of each transmitter type? Sensors ...

Some photoelectric sensors, ultrasonic sensors, and rotary encoders generate a digital dc output called a push-pull signal. The external environment activates the sensor, which, in turn, closes a ...

Usually, when you need to sense something in a project, the answers are straightforward. Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s a sensor for ...

New surface-mount optical sensors increase vertical headroom, enabling more flexible encoder and position-sensing designs across industrial and consumer electronics.
