Obsolete precision reference — sourcing through surplus channel
8.192V shunt reference with ±0.1% initial accuracy
The ±0.1% tolerance places it in the precision tier suitable for ADC reference, DAC scaling, and precision comparator threshold applications where the reference voltage directly sets the conversion accuracy. The 8.192V output is a standard value for data converter references — it maps cleanly to 0xFFFF at 8.192V full-scale in a 16-bit ADC, simplifying the software scaling factor.
Shunt topology and operating conditions
Shunt reference requires an external series resistor. Cathode current range is 95 µA minimum to 15 mA maximum. The SOT-23-3 package (TO-236-3, SC-59, SOT-23-3) is a standard surface-mount footprint.
Noise floor for precision circuits
This is a typical figure for a precision shunt reference at this voltage level — it contributes roughly 0.0016% of full-scale noise in a 16-bit system, which is acceptable for most industrial ADC applications but may require additional filtering for metrology-grade designs targeting 18+ bits.
