FS9952 Data Sheet
1. For the best use of FS9952, please read this data sheet carefully.
2. All application schematics in the data sheet and all component specifications in the
diagram are for reference only. The actual application for the schematic forms,
component specifications and parameters depend on the actual situations to ensure
that it can reach the requirement of design.
3. When use this product to measure the meter, it should be take care of the protection
for over-voltage and over-current on input ends, lest the product and the meter causes
damaged under over-voltage and over-current.
4. “Auto Power Off” of the product is a sleep status. In sleep status, the system still
consumes little current (less than 1μA). It is better to cut off the power if not use for
a long time.
5. FS9952 is a high accuracy and multifunctional ADC with microprocessor. When
apply the product, the anti-interfere problem should be considered during the PCB
design and components layout to reduce external and internal interferes and get the
6. This version is updated in July 2002. It may take a change for some parameters and
schematics according to the improvement and promotion of the product. If so, it will
not be noted actively. For any question, please contact our company directly.
