Current transducers are electrical devices that measure electrical current, which is one of the most important parameters when it comes to measuring electrical power. Avago Technologies\' CR4160-5 is one of the most sophisticated and precise current transducers available in the market. This transducer is designed for industrial and medical applications to provide current measurements over a wide range of frequencies.

CR4160-5 is an accurately calibrated transducer with an accuracy of 0.03%. It utilizes an on-chip based Hall effect technology and a range of PWM signals to provide precise current measurements. The transducer is composed of an integrated circuit (IC), an external trimming circuit placed outside the IC, and an output coil. The IC is a single-chip, bipolar surface mount device containing a Hall plate, amplifier, reference voltage, peak-to-peak output circuit, and a 10.7 Vac temperature sensor. Each of these components plays an important role in the working of the CR4160-5.

The Hall plate is used to measure an input current and is composed of two independent sensing elements. The amplifier provides electrical gain and its transfer function is adjusted with an external trimming circuit, which consists of a potentiometer and two resistors. The reference voltage provides a reference value for the input current and can be adjusted with the trimming circuit as well. The peak to peak output circuit is used to convert the input signal into a proportional output voltage. Lastly, the temperature sensor measures the temperature of the transducer.

CR4160-5 is designed to operate over a wide range of frequencies, from dc up to 400 kHz. It can be used in a variety of industrial, medical, and aerospace applications, making it an ideal choice for any current measurement goals. In addition, the transducer can also be used in the development and evaluation of power electronics components and circuits. The CR4160-5 transducer provides precise current measurements with superb accuracy over a wide range of frequencies, making it one of the most precise current transducers available.
