A Tandem Reference Source (also called a series / 串联 voltage reference) is a three-terminal (VIN, VOUT, GND) precision analog IC that connects in series with the load. It uses an internal feedback-controlled pass element to maintain a highly stable, accurate output voltage regardless of variations in input supply voltage, temperature, or load current.
Application Scope：
1.High-Resolution ADC/DAC:Precision voltage reference for data converters in industrial measurement and instrumentation.
2.Industrial Process Control:4–20 mA current loops,sensor signal conditioning,and PLCs.
3.Automotive Electronics:Engine control units(ECUs),battery management systems(BMS),and infotainment systems(AEC-Q100 qualified).
4.Medical Devices:Portable diagnostic equipment,patient monitors,and precision analytical instruments.
5.Test&Measurement:Oscilloscopes,multimeters,and calibration equipment requiring high accuracy.
6.Battery-Powered Devices:Smartphones,wearables,and IoT sensors needing low power and high stability.
7.Communication Systems:RF signal processing,base stations,and high-speed data acquisition modules.
