Overview CC6904 is a high-performance single-ended output linear current sensor that provides a more effective solution for AC or DC current detection, widely used in industrial, consumer, and communication equipment. CC6904 integrates a high-precision, low-noise linear Hall circuit and a low-impedance main current conductor. When the sampled current flows through the main current conductor, the magnetic field generated induces a corresponding electrical signal on the Hall circuit, and the signal processing circuit outputs a voltage signal, making the product easier to use. The linear Hall circuit is manufactured using an advanced BiCMOS process and includes a high-sensitivity Hall sensor, a Hall signal preamplifier, a high-precision Hall temperature compensation unit, an oscillator, a dynamic offset cancellation circuit, and an amplifier output module. In the absence of a magnetic field, the static output is 50%VCC. Under a supply voltage of 3.3V, OUT can linearly change between 0.33V and 2.97V with the magnetic field, and the linearity can reach 0.4%. The dynamic offset cancellation circuit integrated in CC6904 ensures that the IC's sensitivity is not affected by external pressure and IC packaging stress. CC6904 is available in SOP8 packaging and has an operating temperature range of -40°C to 125°C.
