What are the key features of REF102CPG4?
- Precision 10 V output voltage with ±2.5 mV initial accuracy (±250 ppm) and ultra-low temperature coefficient, enabling 16-bit and higher resolution ADC/DAC reference circuits
- Three-terminal shunt reference topology requiring minimal external components, simplifying PCB design and reducing BOM for benchtop and rack-mount instrumentation
- DIP-8 through-hole package for easy prototyping, socketed testing, and legacy instrument board compatibility without SMT rework equipment
What is REF102CPG4 used for?
REF102CPG4 provides the precision 10 V reference rail for high-accuracy data acquisition systems, calibration instruments, and 16-bit or 18-bit DAC output stages where a stable, low-noise 10 V reference directly determines system accuracy. Its tight ±2.5 mV initial accuracy and low temperature drift make it a standard choice in digital multimeters, programmable voltage sources, and weighing scale signal conditioners. The DIP-8 package is also convenient for laboratory bench instruments and evaluation boards that require socketed components for easy field calibration or swap-out.

Frequently Asked Questions
What output voltage accuracy and temperature coefficient does REF102CPG4 provide for 16-bit ADC reference applications?
REF102CPG4 delivers a 10 V output with an initial accuracy of ±2.5 mV (±250 ppm) and a temperature coefficient of typically 2.5 ppm/°C. At 16-bit ADC resolution where 1 LSB equals approximately 153 µV for a 10 V full-scale reference, this initial error of ±2.5 mV represents about ±16 LSBs and must be trimmed with a trim resistor network, while the low tempco ensures drift stays under 0.5 LSB over a 25 °C temperature excursion.
How does REF102CPG4 compare to REF102AP when selecting a 10 V reference for an industrial calibration standard?
REF102CPG4 is the commercial temperature grade (0 °C to +70 °C) variant rated for ±2.5 mV initial accuracy, while REF102AP is the military/extended grade with a tighter ±1 mV specification and -55 °C to +125 °C range. For industrial calibration standards requiring annual recertification over a 0 °C to +50 °C lab environment, REF102CPG4 is cost-effective; mission-critical aerospace or defense instruments should specify REF102AP to cover wider temperature extremes.
What input supply voltage range does REF102CPG4 require, and how does this constrain power supply design?
REF102CPG4 requires a minimum input supply of +13.5 V to maintain the 10 V output with adequate headroom across its dropout voltage of approximately 3.5 V. Most designs power it from a regulated +15 V rail, which keeps the dropout comfortably within specification and limits quiescent dissipation. Systems operating from a single +12 V supply cannot use REF102CPG4 and should instead consider the REF5010 series with a lower dropout threshold.
Can REF102CPG4 drive a 16-bit DAC output stage directly, and what output current capability does it offer?
REF102CPG4 can source approximately 10 mA of output current, which is sufficient to bias most 16-bit DAC reference inputs directly without a buffer amplifier for loads above 1 kΩ. For DAC designs requiring the reference to drive multiple parallel chips or low-impedance output stages below 1 kΩ, an OPA277 or similar precision unity-gain buffer with sub-1 µV/°C offset should be added to prevent load-dependent output voltage shifts that would exceed the 2.5 mV initial accuracy budget.
