FS9721B

General Description

FS9721B is a high performance, low power consumption and 32/3 digits (2400 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 FS9721B 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.

FS9721B has series data output functions. User can connect the meter to computer to record, analysis, process and print the measured data.
