The PAC1921 Click Board™ is a versatile power monitoring and measuring device intended for the high speed, low latency measurements. This device can measure current, voltage or the power of the connected load. The PAC1921 Click Board™ features an integrated average power measurement, it can output the measured properties in the form of a filtered analog voltage level by using 10-bit DAC, provides 1x to 128x current binary gain, it has an integrated second order input ADC, automatic zero offset, and all the measured values are available through the serial SMBus/I2C interface.
