What are the key features of REF102APG4?
- Precision 10 V output with ±0.1% initial accuracy delivering 9.99 V to 10.01 V for high-resolution ADC and DAC reference applications
- Three-terminal architecture requiring minimal external components for a complete stable reference circuit
- DIP-8 package enabling easy prototyping and socket-based replacement in lab instruments and calibration standards
What is REF102APG4 used for?
The REF102APG4 serves as a high-precision reference in 12-bit and 16-bit ADC/DAC calibration circuits, precision measurement instruments, and industrial data-acquisition systems that require a stable 10 V reference voltage. Its tight ±0.1% initial accuracy eliminates the need for external trimming in most designs, reducing calibration time. It is also used in analog computing modules, signal generators, and comparator threshold-setting circuits where a well-regulated 10 V reference is the foundation for accurate measurements.

Frequently Asked Questions
How accurate is the REF102APG4 output voltage, and does it require external calibration trimming?
The REF102APG4 provides a nominal 10 V output with ±0.1% initial accuracy, meaning the output falls between 9.99 V and 10.01 V without any external adjustment. This tight tolerance is sufficient for most 12-bit and 14-bit ADC reference applications, eliminating the need for trim resistors and reducing assembly cost.
What supply voltage is required to operate the REF102APG4 and maintain regulation?
The REF102APG4 requires an input supply voltage of at least 13.5 V, typically 15 V, to maintain the 10 V output with full accuracy and low dropout. This makes it suitable for ±15 V benchtop instrument power supplies and industrial 24 V rail systems, though it is not compatible with 12 V or lower single-supply designs.
For a 16-bit DAC reference, why is the REF102APG4's 10 V output advantageous compared to a 5 V reference?
A 10 V reference allows a 16-bit DAC to resolve steps of approximately 153 µV per LSB rather than 76 µV, which relaxes noise and layout requirements while still achieving high absolute accuracy. The higher reference voltage also improves signal-to-noise ratio in precision analog output stages driving sensors or actuators with ±10 V ranges.
