LTC6655BHLS8-2.5

The LTC6655BHLS8-2.5 is a fixed 2.5 V voltage reference from Analog Devices (formerly Linear Technology). It’s part of the LTC6655 family and is designed to provide a very stable, low-noise reference for precision analog circuits.
Key points:
- Fixed output: 2.5 V reference for ADC/DAC front ends, instrumentation, and calibration networks.
- Performance: low noise, low temperature drift, high long-term stability, suitable for demanding precision applications.
- Package and grade: 8-pin package with a temperature/grade spec indicated by the BHLS8 suffix (industrial/extended range variants are available in the family).
- Drive and usage: modest output current capability to bias downstream circuitry; not a power regulator—use decoupling and keep traces short. If higher load is needed, buffer with an op-amp.
Applications:
- Precision measurement and calibration
- ADC/DAC references
- Instrumentation and test equipment
Design tips:
- Place a bypass/decoupling capacitor close to the part.
- Follow the datasheet for recommended load, bypass values, and wiring.
- Compare with other LTC6655 variants to match your exact accuracy and tempco needs.

Key features of LTC6655BHLS8-2.5:
- Fixed 2.5 V output voltage
- Ultra-low noise and high accuracy
- Very low drift with temperature and long-term stability
- Excellent line and load regulation
- Low quiescent current
- Wide operating temperature range suitable for precision use
- 8‑lead BHLS8 package (lead-free, RoHS compliant)
- Ideal for precision references in ADC/DACs and instrumentation
Note: For exact numbers (initial accuracy, tempco, noise, and supply range), please consult the LTC6655 datasheet for the BHLS8-2.5 variant.

An 8‑lead MSOP package (MSOP‑8), RoHS compliant.

- Pin count: 8 pins (BHLS8 package)
- Function: Fixed 2.5 V precision voltage reference. It uses V+ (supply) and GND; VOUT provides the 2.5 V reference output. The remaining pins are typically no-connect/test pins in this package.

Manufacturer: Analog Devices, Inc. (ADI). It now owns the Linear Technology product line that includes the LTC6655 family.
What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.
