Frequently Asked Questions
What makes the 0.25 ppm/°C temperature drift of the LTC6655LNBHMS8-2.5 significant for 24-bit ADC reference applications?
At 0.25 ppm/°C, the LTC6655L output shifts only 0.025 mV across a 40 °C temperature excursion, which represents less than 1 LSB for a 24-bit ADC with a 2.5 V full-scale range. Competing references at 5 ppm/°C would introduce 20 times more drift error, directly degrading conversion accuracy in precision measurement systems.
How much output current does the LTC6655LNBHMS8-2.5 source, and can it drive multiple precision loads simultaneously?
The device sources up to 5 mA of output current, which is enough to simultaneously supply the reference input of a 24-bit ADC, a precision DAC, and a few resistive divider networks without significant voltage droop. For higher current loads, a unity-gain buffer amplifier is recommended to maintain the 0.25 ppm/°C drift specification.
When would a designer select the LTC6655LNBHMS8-2.5 over a standard bandgap reference rated at 10 ppm/°C?
For systems where measurement uncertainty must stay below 10 ppm over the full industrial temperature range of -40 °C to 85 °C, a standard 10 ppm/°C reference introduces 1250 ppm worst-case drift versus just 31 ppm for the LTC6655L. This 40× improvement justifies its cost premium in metrology, aerospace, and medical-grade equipment where recalibration cycles must be minimized.
