The Analog Devices LTC6655BHMS8-4.096#PBF is a precision bandgap voltage reference providing a fixed 4.096V output with an initial accuracy of ±0.025% and a maximum temperature coefficient of 2ppm/°C. It operates within a supply range from VOUT + 0.5V to 13.2V, featuring low dropout capability and bidirectional current sourcing/sinking of ±5mA. The device includes a shutdown mode consuming less than 20µA and is housed in an 8-lead plastic MSOP package.
Verify the specific suffix #PBF indicates tube packaging rather than tape and reel. Confirm the 'B' grade designation matches the required ±0.025% initial accuracy specification. Ensure the MSOP package type aligns with the target PCB footprint requirements before finalizing procurement orders.
Select this component when a fixed 4.096V reference with ultra-low drift is required. The B-grade version offers tighter initial accuracy compared to the C-grade alternative. Consider the LS8 hermetic package if superior long-term stability and humidity resistance are necessary for the application environment.
This part belongs to the LTC6655 family of precision voltage references designed for demanding industrial and automotive environments. The family spans various output voltages including 1.25V, 2.5V, and 5V, all sharing similar low-noise and low-drift performance characteristics across the –40°C to 125°C operating temperature range.
LTC6655CHMS8-4.096#PBF offers the same functionality with slightly relaxed accuracy specifications.
