Applications
The LTC6655BHMS8-2.048#PBF is used as the precision reference in high-resolution data acquisition systems, such as 16-bit to 24-bit ADC front ends in test and measurement instruments, where output voltage accuracy better than 1 mV and ultra-low noise are mandatory. It is well-suited for calibration equipment, medical diagnostic devices, and industrial weighing systems that require a stable 2.048 V reference tied to binary-scaled full-scale ranges. The compact MSOP-8 footprint allows integration into portable instruments and multi-channel data loggers with tight PCB area constraints.

Frequently Asked Questions
What output voltage accuracy does the LTC6655BHMS8-2.048#PBF provide for ADC reference use?
The LTC6655BHMS8-2.048#PBF outputs between 2.0474 V and 2.0485 V, giving a total accuracy span of approximately 1.1 mV. This tight tolerance makes it an excellent precision reference for 16-bit and 24-bit SAR or delta-sigma ADCs where a stable 2.048 V full-scale reference directly maps to binary millivolt resolution, minimizing gain error in data acquisition channels.
Why is the 2.048 V output of LTC6655BHMS8-2.048#PBF particularly useful in digital measurement systems?
A 2.048 V reference is preferred in digital measurement systems because it is a binary-friendly value: 2.048 V divided by 2^11 gives exactly 1 mV per LSB for an 11-bit ADC, and divided by 2^12 gives 0.5 mV per LSB. This simplifies firmware scaling to integer millivolts and reduces software complexity in 12-bit, 16-bit, and 24-bit conversion chains used in industrial and laboratory instruments.
How does the LTC6655BHMS8-2.048 compare to a 2.5 V reference when driving a 16-bit ADC?
When driving a 16-bit ADC, a 2.048 V reference sets the LSB to exactly 31.25 µV, while a 2.5 V reference gives a non-binary 38.15 µV LSB that requires software scaling. The LTC6655BHMS8-2.048 therefore eliminates fractional LSB rounding errors in binary-scaled measurements, and its ultra-low noise is critical to achieving the full 16-bit noise-free code resolution of 96 dB SNR.
What package does LTC6655BHMS8-2.048#PBF use and what are its key assembly considerations?
The LTC6655BHMS8-2.048#PBF is housed in an MSOP-8 (Micro Small Outline Package) with 8 pins on a 0.65 mm pitch. The compact body of approximately 3 mm × 3 mm requires careful PCB land pattern design and low-ESR bypass capacitors of at least 1 µF on the output to ensure stability and minimize noise at the 2.048 V reference node.
