Frequently Asked Questions
What output voltage and temperature coefficient does the LTC6655LNCHMS8-2.5 provide for precision ADC reference applications?
The LTC6655LNCHMS8-2.5 provides a 2.5 V precision output voltage with a maximum temperature coefficient of 0.25 ppm/°C. This exceptional stability means the reference voltage shifts by less than 0.625 µV per degree Celsius, making it well-suited as a reference for 16-bit and 18-bit ADC and DAC systems where voltage accuracy directly determines measurement resolution.
How does the noise performance of the LTC6655LNCHMS8-2.5 benefit high-resolution data acquisition designs?
The LTC6655LNCHMS8-2.5 achieves an ultralow output noise of 0.25 µVpp in the 0.1 Hz to 10 Hz frequency band. This extremely low 1/f noise floor prevents reference noise from limiting the effective number of bits (ENOB) in precision 18-bit ADC designs, ensuring that measurement accuracy is constrained only by the converter itself rather than the reference source.
Which package and supply configuration does the LTC6655LNCHMS8-2.5 use, and how does it fit into a precision analog board?
The LTC6655LNCHMS8-2.5#TRMPBF is housed in an 8-pin MSOP package and supplied in tape-and-reel format for automated SMT assembly. It operates from a supply voltage range typically from 3 V to 13.2 V and delivers a stable 2.5 V reference output, fitting easily into compact precision analog boards alongside 16-bit or 18-bit ADC and DAC ICs in instrumentation and data acquisition systems.
