Description:

CSH-12 – is Hall effect current sensor IC applied in non-contact sensing for provide AC or DC current measuring in PCB conductors. CSH-12 provides Hall effect technology for magnetic field measure, signal amplification, ADC/DAC signal conversion (12-bit SAR A/D converter), ratiometric output (after D/A conversion), programmable PWM output, digital SPI interface output and two-level programmable comparator output. The CSH-12 has a 4-pin serial peripheral interface (SPI) for programming EEPROM registers and read measuring data. Package QLCC-32 (package dimensions:10,7х10,7х2,2 mm) or chip die (chip die size 3,7x3,7x0,3 mm).
