FUNCTIONAL DESCRIPTION
The SA9122E is a CMOS mixed signal Analog/Digital integrated circuit, which performs
power/energy calculations across a power range of 1000:1, to an overall accurancy of
better than Class 1, and includes a seperate 64 segment LCD display driver function.
The integrated circuit includes all the required functions for 1-phase power and energy
measurement such as two oversampling 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 SA9122E generates pulses, the
frequency of which is proportional to the power consumption. Two frequency outputs
(FOUT1 and FOUT2) are available, with additional frequency options available on
request. The pulse rate follows the instantaneous power measured.
The separate Liquid Crystal Display driver function included on-chip, drives up to 64
segments on a 4 track muliplexed backplane display, programmable via a serial interface
having a RS232 protocol.
