FS9922_DMM4
General Description
FS9922_DMM4 is a high performance, low power consumption and 34/5 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.
Built-in dual Analog to Digital Converter, one is a high accuracy ADC for main measurement; the other is a high speed ADC whose measurement result shows by a 41 segment analog section bar that can respond fast. Due to FS9922_DMM4 has an embedded microprocessor so that can control the logic function, assemble various measurement functions.
