Features  Operating voltage range: 4.5~5.5V  The reference has two modes: built-in VREF output and external VREF input:  When the built-in VREF output is used, the typical value of VOE is ±5mV  When the external VREF input is used, the static output voltage of VOUT remains consistent with it, and the gain does not fluctuate with VCC  The voltage range is effective when the VREF input range is 1V~4V  The external reference takes effect when the external sink current >1.5mA  Wide measurement range, linearity better than 0.5%  1.3MHz chopping frequency, high bandwidth, low noise, signal bandwidth up to 200kHz  Low power consumption, typical static operating current of IC <25mA  Sensitivity, static output voltage is user-programmable, 4 programming times  Operating temperature range: -40~125°C, storage temperature range -55~150°C  Strong anti-interference ability  Strong resistance to mechanical stress, magnetic parameters will not shift due to external pressure  ESD (HBM) 4kV, ESD(MM)200V Applications  Current sensor  Magnetic encoder  Gear sensor  Displacement measurement  Rudder

The CC6531 is a high-performance, programmable linear Hall sensor IC, manufactured using an advanced BiCMOS process. It boasts a high Hall coefficient and integrates 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. The CC6531 utilizes advanced adaptive Hall temperature compensation technology, enabling normal operation between -40°C and 125°C. It features a wide linear output range; under a 5V supply voltage, the VOUT output linearly varies between 0.5V and 4.5V with the magnetic field, achieving linearity as high as 0.5%. The integrated dynamic offset cancellation circuit ensures that sensitivity and static output voltage are unaffected by external pressure and packaging stress. With a chopping frequency of 1.3MHz and a bandwidth of 200kHz, it offers fast response speeds. The chip integrates an EEPROM for programming sensitivity and static signal output, expanding user applications. The EEPROM can be programmed 4 times. The CC6531 is available in a TO-94 package, operates within a temperature range of -40°C to 125°C, and complies with halogen-free, lead-free, and RoHS regulations.
