General Description

FS9952_LP1 is a high performance, low power consumption and 31/2 digits (1999 Counts) Analog to Digital Converter that built-in a microprocessor (ADC+MCU). It contains 8-bits microprocessor, low noise OPAMP, high regulated bandgap, regulator, measurement switch, function control circuit, buzzer driver, oscillation circuit, backlight display control/driver circuit, LCD display driver and so on.

Due to FS9952_LP1 has a 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 a fully manual measurement meter.

FS9952_LP1 has a AC/DC and ℉/℃ select function. This is convenience for user to enter the required measurement mode.
