What are the key features of REF102CP?
- Ultra-low 2.5 ppm/°C maximum temperature coefficient ensures sub-millivolt output stability across the full industrial temperature range
- Precision 10 V output trimmed to ±2.5 mV (9.9975 V to 10.0025 V) suits 12-bit to 16-bit ADC and DAC reference applications
- Wide 11.4 V to 36 V input range accommodates unregulated bench supplies and industrial ±15 V dual-rail systems in an 8-pin DIP footprint
What is REF102CP used for?
The REF102CP is a benchmark voltage reference for precision data-acquisition systems, calibration equipment, and high-accuracy 16-bit ADC/DAC designs where output drift below 5 ppm/°C is mandatory. Its 10 V output conveniently scales to standard ADC reference voltages using a single resistor divider, reducing external component count. The through-hole DIP-8 package also makes it straightforward to socket for field calibration in test and measurement instrumentation.

Frequently Asked Questions
How does the REF102CP 2.5 ppm/°C drift affect a 16-bit ADC system over a 50°C temperature range?
With a 2.5 ppm/°C temperature coefficient and a 10 V output, the REF102CP introduces a maximum drift of 1.25 mV over a 50°C temperature swing, which corresponds to roughly 8 LSBs in a 16-bit system referenced to 10 V. By contrast, a 10 ppm/°C reference would drift 5 mV over the same range, degrading a 16-bit ADC measurement by more than 32 LSBs and potentially violating the ±1 LSB accuracy specification.
What minimum input supply voltage does the REF102CP require and how does that constrain power-supply design?
The REF102CP requires a minimum input voltage of 11.4 V to maintain its regulated 10 V output, meaning the supply must be at least 1.4 V above the reference output to keep the device in regulation. In dual-supply ±15 V systems this headroom is comfortable, but in single-supply designs operating from 12 V rails, engineers must account for worst-case supply droop to ensure the device never drops below the 11.4 V floor.
In a precision calibration setup, when should REF102CP be chosen over a 5 V reference with the same drift spec?
REF102CP's 10 V output is preferred in calibration setups when the ADC or DAC full-scale range is 10 V, because directly referencing to 10 V eliminates gain-scaling errors from resistor dividers that would add their own temperature and tolerance errors. A 5 V reference used at 10 V full scale requires a 2x gain stage, introducing at least 10 ppm/°C to 25 ppm/°C additional drift from resistor mismatch, negating the benefit of a low-drift reference. The 8-pin DIP package of the REF102CP also simplifies socketing for periodic calibration checks.
