Frequently Asked Questions
What output voltage accuracy and temperature drift does the LTC6655CHLS8-2.5#PBF provide?
The LTC6655CHLS8-2.5#PBF delivers a 2.5 V output with 0.05% (1.25 mV) initial accuracy and a temperature coefficient of 2 ppm/°C, keeping the reference stable across the 0°C to 70°C commercial temperature range for precision 16-bit and 24-bit ADC applications.
Why is the HLS8 ceramic package chosen for the LTC6655CHLS8-2.5 over plastic alternatives?
The 8-lead ceramic LCC (HLS8) package offers hermetic sealing that eliminates moisture ingress, which is critical for long-term voltage reference stability in industrial instrumentation. Plastic packages can absorb humidity and shift output by several ppm over time, whereas the ceramic package maintains output integrity at the 2.5 V ±1.25 mV level indefinitely.
Which high-resolution converter designs benefit most from the LTC6655CHLS8-2.5#PBF noise performance?
The LTC6655CHLS8-2.5#PBF is optimized for 16-bit to 24-bit SAR and delta-sigma ADCs, where its 0.25 ppm/√Hz noise spectral density keeps the wideband noise below 1 µV RMS in a 10 kHz bandwidth, preventing the reference from limiting converter effective number of bits (ENOB) in precision measurement systems.
