Frequently Asked Questions
What output voltage accuracy does LTC6655CHMS8-3#PBF guarantee over its operating range?
The LTC6655CHMS8-3#PBF guarantees output voltage between 2.9985 V and 3.0015 V, representing ±1.5 mV accuracy at 3.0 V nominal. This tight tolerance makes it suitable as a reference for 16-bit and 18-bit ADCs where even small reference errors translate to measurable conversion inaccuracies.
For which resolution ADC or DAC applications is LTC6655CHMS8-3#PBF most appropriate?
LTC6655CHMS8-3#PBF is particularly suited for 16-bit, 18-bit, and 20-bit ADC and DAC designs that require a stable, low-noise 3.0 V reference. Its ultra-low noise characteristic, typically below 1 µV RMS in the 0.1 Hz to 10 Hz band, prevents reference-induced dither from degrading converter resolution.
How does the MSOP-8 package affect thermal performance in precision reference designs?
The 8-pin MSOP package provides a small PCB footprint with moderate thermal dissipation. Designers should limit self-heating by keeping quiescent current draws low, and place a 10 µF output capacitor close to the reference output pin to maintain stability and minimize noise peaking above 100 kHz.
When is LTC6655CHMS8-3#PBF a better choice than a simple Zener-based 3 V reference?
A Zener-based reference typically has noise in the millivolt range and initial accuracy of ±5% or worse, while LTC6655CHMS8-3#PBF offers ±500 ppm initial accuracy and ultra-low noise below 1 µV RMS. This makes it indispensable in precision measurement systems, medical sensors, and weigh-scale designs where 3.0 V reference stability directly limits system accuracy.
