What are the key features of LTC6655BHMS8-2.048#TRPBF?
- Ultra-low output noise below 2 µV peak-to-peak in the 0.1 Hz to 10 Hz band enabling high-resolution 18-bit ADC reference applications
- 2.048 V output trimmed to a tight 2.0474 V to 2.0485 V window delivering sub-1 LSB initial accuracy for 16-bit data acquisition systems
- Low temperature coefficient ensuring stable 2.048 V output across industrial and automotive temperature ranges without external trim
- MSOP-8 compact footprint with single-output three-terminal architecture minimising board area in precision measurement instruments
What is LTC6655BHMS8-2.048#TRPBF used for?
The LTC6655BHMS8-2.048#TRPBF is used as a precision reference in 16-bit and 18-bit ADC or DAC circuits found in laboratory test instruments, precision data loggers, and medical diagnostic equipment where reference noise directly limits system dynamic range. Its 2.048 V output is chosen specifically to set 1 mV per LSB full-scale on 12-bit and 16-bit converters without additional scaling, simplifying firmware calibration. The device is also deployed in precision strain-gauge bridges, RTD conditioning circuits, and industrial process controllers requiring a reference stable to within 5 ppm across the operating temperature range.

Frequently Asked Questions
What output noise specification does LTC6655BHMS8-2.048 deliver, and why does that matter for 18-bit ADC designs?
The LTC6655BHMS8-2.048 produces less than 2 µV peak-to-peak noise in the 0.1 Hz to 10 Hz band, which is well below the 4 µV LSB size of an 18-bit ADC referenced to 2.048 V. Reference noise that exceeds 0.5 LSB degrades effective number of bits, so this device preserves the full 18-bit dynamic range without requiring a separate reference noise filter.
How accurately does LTC6655BHMS8-2.048 hold its 2.048 V output, and what initial error does a designer budget for?
The output is trimmed to a band of 2.0474 V minimum and 2.0485 V maximum at 25 degrees C, a span of 1.1 mV or roughly 0.05% initial accuracy. For a 16-bit ADC this corresponds to less than 33 LSB initial offset, which most system calibration routines can remove in one factory trim cycle, eliminating the need for a discrete trimmer potentiometer.
In what precision measurement applications is LTC6655BHMS8-2.048 preferred over a 2.5 V or 3.0 V reference?
The 2.048 V value is selected for data acquisition boards using 12-bit, 14-bit, or 16-bit ADCs because it sets a binary-friendly full-scale of exactly 0.5 mV or 0.031 mV per LSB, simplifying microcontroller scaling code to a single bit-shift rather than a floating-point multiply. Instruments requiring direct millivolt-per-count readings at 12-bit resolution benefit most from this 2.048 V reference value.
What package does LTC6655BHMS8-2.048#TRPBF use, and how does it compare to TO-92 references in a compact instrument PCB?
The device is packaged in an MSOP-8 measuring 3 x 3 mm, which occupies approximately 9 mm2 of PCB area compared to the 30 mm2 or more required by a through-hole TO-92 reference. The MSOP-8 also enables automatic SMT assembly and eliminates the lead-forming step, reducing assembly cost per board by roughly 5 seconds of hand-placement time at scale.
