Key Features
- 4.096 V output with 0.05% initial accuracy and 2 ppm/°C maximum temperature coefficient for precision measurement systems
- Ultra-low noise of 0.25 µVRMS (0.1 Hz to 10 Hz) enabling high-resolution ADC reference performance
- Low dropout operation from 4.5 V input for 4.096 V output, suitable for 5 V single-supply systems
- MSOP-8 package with tape-and-reel (TR) and Pb-free (MPBF) for automated SMT assembly
Applications
The LTC6655LNBHMS8-4.096 is used as a precision voltage reference for 16-bit and 18-bit ADCs in data acquisition systems, medical instrumentation, and precision industrial measurement equipment. Its 2 ppm/°C drift and ultra-low noise floor suit laboratory-grade calibration references and high-resolution DAC outputs in test-and-measurement instruments. Precision weighing systems, process control transmitters, and high-accuracy power meters also rely on this reference for stable 4.096 V excitation.

Frequently Asked Questions
What output voltage and accuracy does the LTC6655LNBHMS8-4.096 provide for precision ADC references?
The device provides a 4.096 V output with 0.05% initial accuracy and a maximum temperature coefficient of 2 ppm/°C, making it suitable for driving 16-bit to 18-bit SAR ADCs in precision measurement and data acquisition systems.
How low is the noise of the LTC6655LNBHMS8-4.096 and why does it matter for high-resolution designs?
The LTC6655LNBHMS8-4.096 produces only 0.25 µVRMS of noise in the 0.1 Hz to 10 Hz band, which is critical for high-resolution 18-bit or 20-bit ADC designs where reference noise directly limits the achievable signal-to-noise ratio.
What is the minimum input voltage required to maintain the 4.096 V output of the LTC6655LNBHMS8-4.096?
The reference requires a minimum input supply of approximately 4.5 V to regulate the 4.096 V output, allowing direct use from a standard 5 V system rail without additional boosting while maintaining 2 ppm/°C drift accuracy.
When is the LTC6655LNBHMS8-4.096 preferred over a 2.5 V reference in precision system designs?
A 4.096 V reference is preferred when the ADC full-scale range maps cleanly to 4.096 V, simplifying binary-coded conversion math at 1 mV per count for 12-bit systems or 62.5 µV per count for 16-bit systems, reducing firmware scaling complexity.
