Applications
The LTC6655BHMS8-5#TRPBF is designed for high-resolution data acquisition systems and precision instrumentation where reference noise floors must remain below the least significant bit of 16-bit to 24-bit ADCs. Its ultra-low 0.1 Hz to 10 Hz noise specification makes it the preferred reference for weigh scales, electrochemical analyzers, and medical diagnostic equipment that must resolve microvolt-level signals. The device is also used as the primary reference in precision DAC circuits for automated test equipment and laboratory calibration standards requiring traceable 5 V accuracy.

Frequently Asked Questions
How does the noise performance of LTC6655BHMS8-5#TRPBF compare to standard voltage references when driving a 24-bit ADC?
The LTC6655BHMS8-5#TRPBF achieves less than 2 µVpp noise from 0.1 Hz to 10 Hz, which is below the 1 LSB noise floor of most 24-bit ADCs referenced to 5 V, where 1 LSB equals approximately 0.3 µV. In contrast, standard bandgap references typically exhibit 10 µVpp to 30 µVpp in the same band, which would add several LSBs of error to the ADC output and degrade effective number of bits. This makes the LTC6655BHMS8-5#TRPBF the preferred choice for precision weigh scales and chemical analyzers.
What output voltage accuracy does the LTC6655BHMS8-5#TRPBF provide, and why does this matter for system calibration?
The LTC6655BHMS8-5#TRPBF guarantees an output voltage between 4.9987 V and 5.0012 V, a ±2.5 mV accuracy window representing ±0.025% initial error. For a calibration system using a 16-bit ADC with a 5 V full-scale range, this level of reference accuracy contributes less than 0.025% gain error, which is well within the ±0.1% system budget of most industrial measurement instruments, eliminating the need for factory trim.
In what board space does the LTC6655BHMS8-5#TRPBF fit, and how does the MSOP-8 package compare to full-size SO-8 alternatives?
The LTC6655BHMS8-5#TRPBF is housed in an 8-pin MSOP package measuring approximately 3 mm x 3 mm, which is roughly 50% smaller in board area than a standard SO-8 footprint of 5 mm x 4 mm. This compact size is valuable in portable precision instruments such as handheld multimeters, field calibrators, and wearable biosensors where PCB real estate is strictly limited but 5 V reference performance cannot be compromised.
How should a designer configure the LTC6655BHMS8-5#TRPBF to achieve its minimum noise specification in a data acquisition front end?
To reach the datasheet specification of under 2 µVpp from 0.1 Hz to 10 Hz, the LTC6655BHMS8-5#TRPBF requires a 10 µF or larger low-ESR capacitor at its output pin combined with a 100 nF ceramic bypass capacitor placed within 2 mm of the IC. The three-terminal structure allows the designer to insert an optional RC filter between the force and sense lines to further attenuate high-frequency noise above 10 Hz, which is useful when the ADC input samples at rates exceeding 10 kSPS and aliasing of broadband reference noise would otherwise raise the noise floor.
