Key Features
- Ultra-low noise output: 0.25 µVRMS (0.1 Hz to 10 Hz) for high-resolution ADC and DAC reference applications
- ±0.05% initial accuracy with 2 ppm/°C temperature drift for stable 3.0 V output across -40°C to +125°C
- Compact MSOP-8 package reduces PCB footprint while delivering precision voltage reference performance
- Output current capability of ±5 mA supports multiple simultaneous loads in instrumentation systems
Applications
The LTC6655CHMS8-3#TRPBF is designed for high-resolution data acquisition systems, precision instruments, and medical measurement equipment where a stable, low-noise 3.0 V reference is essential for 16-bit or higher ADC accuracy. Its ultra-low 0.25 µVRMS noise floor ensures minimal degradation of dynamic range in audio analyzers and industrial sensor signal chains. The part is also commonly used in portable test equipment and calibration references where the MSOP-8 size and wide temperature range from -40°C to +125°C provide both board space savings and reliable field operation.

Frequently Asked Questions
What output voltage accuracy and noise performance does the LTC6655CHMS8-3#TRPBF deliver for ADC reference use?
The LTC6655CHMS8-3#TRPBF provides a 3.0 V output with ±0.05% initial accuracy and an ultra-low noise density of just 0.25 µVRMS from 0.1 Hz to 10 Hz, making it suitable as a reference for 16-bit and 18-bit ADCs where noise-floor degradation directly limits measurement resolution.
Over what temperature range does the LTC6655CHMS8-3#TRPBF maintain its 2 ppm/°C temperature coefficient?
The LTC6655CHMS8-3#TRPBF maintains a 2 ppm/°C temperature coefficient across its full commercial operating range of 0°C to +70°C, with the C-grade suffix denoting this commercial temperature screening. For systems requiring stable reference voltage in environments with significant ambient temperature swings, the 2 ppm/°C drift ensures the 3.0 V output shift stays within a few millivolts across the full range.
How does the MSOP-8 package of the LTC6655CHMS8-3#TRPBF compare to SOT-23 references in terms of board space and output drive?
The MSOP-8 footprint is larger than a SOT-23 but provides a dedicated output trim pin and additional bypass capacitor pins, enabling better noise filtering and easier trimming for precision calibration. More importantly, the 8-pin configuration allows the LTC6655CHMS8-3#TRPBF to deliver ±5 mA output current, compared to the ±1 mA typical of SOT-23 references, supporting multiple converter loads from a single 3.0 V reference.
