What are the key features of REF3240AMDBVREPG4?
- 4.096 V precision output voltage with ±2 mV initial accuracy enables direct 12-bit ADC reference without trimming
- Ultra-low 100 µA supply current suits always-on data acquisition systems and battery-powered instruments
- Compact SOT-23-6 package fits tight PCB layouts in portable medical and industrial measurement devices
What is REF3240AMDBVREPG4 used for?
The REF3240AMDBVREPG4 provides a stable 4.096 V reference for 12-bit and 16-bit ADCs in precision industrial measurement instruments, where its tight output accuracy of 4.088 V to 4.104 V eliminates the need for factory calibration trim. Its low supply current makes it suitable for battery-operated handheld meters, data loggers, and portable medical diagnostic equipment. The SOT-23-6 package also fits signal conditioning boards in motor drive systems where compact board area is required alongside the main MCU.

Frequently Asked Questions
What is the output voltage tolerance of REF3240AMDBVREPG4 and how does it affect 12-bit ADC accuracy?
The REF3240AMDBVREPG4 specifies an output voltage range of 4.088 V to 4.104 V, representing an initial accuracy of ±2 mV around the 4.096 V nominal. For a 12-bit ADC with a 4096-step full scale, this ±2 mV error corresponds to a worst-case reference error of ±2 LSB, which is acceptable for most industrial measurement applications without factory calibration.
How does the 100 µA supply current of REF3240AMDBVREPG4 compare in a battery-powered data logger with always-on sensing?
At 100 µA continuous supply current, the REF3240AMDBVREPG4 consumes 2.4 mWh per day from a 3.6 V source. In a device powered by two AA batteries (2400 mAh combined), the reference alone would contribute less than 2% of total battery drain over a one-year operational period, making it negligible compared to radio or display subsystems drawing milliamps.
For a precision weighing scale design, how does REF3240AMDBVREPG4 support ratiometric load-cell measurements?
In a ratiometric load-cell configuration, the same 4.096 V reference supplies both the ADC reference input and the load-cell excitation voltage. Since both signals track together, any slow supply drift cancels out in the ratio calculation. The REF3240AMDBVREPG4's tight ±2 mV initial accuracy and low temperature coefficient (typically 20 ppm/°C) ensure that the reference remains stable enough for 14-bit to 16-bit resolution weighing cells across an industrial -40°C to 85°C temperature range.
