4000 Counts Auto Rang DMM IC

FS9721_LP1 is a high performance, low power consumption, 33 /4 digits (4000 Counts) Analog/Digital Converter (ADC+MCU) that is embedded Microprocessor It contains 8 bit Microprocessor low noise and high stability operation Amplifier AC conmutation operation Amplifier voltage promotion and voltage regulated power source, high stability bandgap, auto measurement Switch and function control circuit, buzzer driver circuit, Clock Oscillator circuit, Backlight Display control circuit, LCD Display driver circuit and so on. Due to FS9721_LP1 is embedded Microprocessor so that it CAN control the Logic function during passing I/O. Measurement functions CAN be combined differently by using MEA1MEA4 pins and CAP pin code; through the setting to the code CAN build the fully auto and manual measurement meter. There are Range, Select, Hold, Rel, BLCTR, Hz/Duty and Reset keys so that you CAN fulfil measurement selection, functions Switch data hold, Backlight Display relative value, frequency and duty cycle measurement, reset and so on functions through these keys. FS9721_LP1 also has auto power-off function. If there is no any action in 15 minutes for the Switch or keys of the meter, the system will enter the sleeping mode to save power. FS9721_LP1 is embedded Display driver circuit that is designed for driving LCD FS9721_LP1 is manufacted by large intergrated circuit technology that has rised hugely the reliability of product and made the design be easy and the volume be small; the system takes 3V power source of low consumption for battery supply that is fit especially to the palm mode meter. FS9721_LP1 is a multi-measurement AC/DC converter that embedded the Microprocessor Only less addition of external components, you CAN constitute a high accuracy, mult-function and low cost meter.
