FS970X

General Description

FS970X is a series of Digital Multi-function Meter (DMM) chip. The core is a high resolution GU ADC combined with function network, operational amplifiers, digital filter, crystal oscillation circuit, digital control logic, and microprocessor interface.

FS970X ADC includes not only high-resolution output to achieve accurate measurement, but high-speed ADC output to display the bar graph of digital meter and to measure +/- peak hold.

Combined with a microprocessor, FS970X can function as an auto-range DMM to measure DC/AC voltage, DC/AC current, resistance, frequency, peak hold and diode, etc. In addition, it includes several sets of programmable ADC direct input to expand product applicability.
