... A/D converters for the voltage and current sense inputs, power calculation and energy integration. Internal offsets are eliminated through the use of cancellation procedures. The SA2002H generates pulses, the frequency of which is proportional to the measured power consumption. One frequency output (FOUT) is available. The pulse rate follows the instantaneous power consumption measured ...

... INPUT SIGNALS VREF A bias resistor of 24k set optimum bias conditions on chip. Calibration of the SA2002H should be done on the voltage input as described in Typical Applications. Current sense input (IIP and IIN) Figure 6 shows the typical connections for the current sensor input. The resistor R1 and R2 define the current level into the current sense inputs of the SA2002H ...

... The meter is designed for 220V/40A I operation. The most important external MAX components for the SA2002H integrated circuit are the current sense resistors, the voltage sense resistors as well as the bias setting resistor. BIAS RESISTOR R13 defines all on-chip and reference currents. With R13=24k , optimum conditions are set ...
