General Description

FS9721_LP1 is a high performance, low power consumption and 33/4 digits (4000 Counts) Analog to Digital Converter that built-in a microprocessor (ADC+MCU). It contains 8-bits microprocessor, low noise OPAMP, high regulated bandgap, regulator, auto measurement switch, function control circuit, buzzer driver, oscillation circuit, backlight display control/driver circuit, LCD display driver and so on.

Due to FS9721_LP1 has an embedded microprocessor so that can control the logic function, assemble various measurement functions. Through the setting to the code can build a fully auto measurement meter and fully manual measurement meter.

FS9721_LP1 takes low power voltage to reach low consumption and is convenient to use the power supply of battery, especially is proper for use on the palm mode meter.
