Overview
The LTC6655CHMS8-4.096#TRPBF is a precision bandgap voltage reference from Analog Devices, offering an output of 4.096V with ±0.05% initial accuracy and a maximum temperature coefficient of 5ppm/°C. It operates within a supply range of VOUT + 0.2V to 13.2V, providing source and sink currents up to ±5mA. The device features low noise (0.67ppm RMS) and is housed in an 8-lead MSOP package. Designed for –40°C to 125°C operation, it includes a shutdown mode consuming less than 20µA.
Feature Summary
- Advanced curvature compensation ensures high accuracy and predictable temperature characteristics.
Applications
- Instrumentation and test equipment
- High resolution data acquisition systems
- Precise battery monitors
Procurement Notes
Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the 'C' grade designation matches the required ±0.05% accuracy specification. Ensure the MSOP-8 package variant aligns with PCB footprint requirements. Cross-reference the full part number against current manufacturer availability lists.
Selection Notes
Select this component when a 4.096V output is required with moderate drift specifications. The CHMS8 variant provides standard plastic packaging suitable for general industrial use. Consider the LTC6655LN series if lower wideband noise performance is necessary for the application.
Part Context
This part belongs to the LTC6655 family of precision references, which are designed for high-resolution measurements. The family includes options with varying accuracies and packages, such as the hermetic LS8. The CHMS8-4.096 specifically targets applications needing stable voltage generation without calibration.
Replacement Considerations
LTC6655BHMS8-4.096#TRPBF offers higher accuracy at ±0.025%. LTC6655CHMS8-4.096#PBF is the same electrical part but in tube packaging.
FAQ
What is the minimum dropout voltage for this part?
The minimum input-to-output differential voltage is 0.2V when sourcing or sinking current.
How does the SHDN pin function?
Tying the SHDN pin to ground activates shutdown mode, reducing supply current to under 20µA. An internal pull-up enables normal operation if left unconnected.
