Frequently Asked Questions
What output voltage accuracy and noise performance does the LTC6655BHMS8-2.5#TRPBF provide?
The LTC6655BHMS8-2.5#TRPBF provides a 2.5 V output with a tolerance of ±0.05%, corresponding to an output range of 2.4993 V to 2.5006 V. Its ultra-low-noise specification of 0.25 µVRMS (0.1 Hz to 10 Hz) ensures it does not degrade the performance of 16-bit to 24-bit ADCs in precision measurement applications.
How does the LTC6655BHMS8-2.5#TRPBF's noise specification benefit high-resolution ADC designs?
With only 0.25 µVRMS of low-frequency noise from 0.1 Hz to 10 Hz, the LTC6655BHMS8-2.5#TRPBF contributes negligible reference noise to 24-bit ADC designs where the LSB voltage at 2.5 V full-scale is approximately 0.15 µV. This keeps the reference noise contribution below 2 LSBs, preserving the full dynamic range of high-resolution sigma-delta and SAR converters.
What package does the LTC6655BHMS8-2.5#TRPBF use, and is it RoHS compliant?
The LTC6655BHMS8-2.5#TRPBF is housed in an 8-pin MSOP (PDSO-G8) surface-mount package with a lead-free (e3) JESD-609 code. The tape-and-reel (TRPBF) suffix indicates it is supplied in reel packaging for automated SMT assembly, though the Pbfree Code field notes non-standard lead finish — verify the specific lead finish against your RoHS application requirements.
Which precision measurement applications are best served by the LTC6655BHMS8-2.5#TRPBF 2.5 V reference?
The LTC6655BHMS8-2.5#TRPBF is best suited for weigh-scale instrumentation, medical diagnostic equipment, industrial 4-20 mA sensor transmitters, and precision calibration references where a stable 2.5 V rail with less than 1 µVRMS noise and a tight initial accuracy of ±0.05% is required across a -40°C to 125°C operating temperature range.
