Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the BC grade designation corresponds to the required 5ppm/°C temperature coefficient and 0.05% accuracy for your design. Ensure the industrial temperature range meets system requirements. Check for RoHS compliance status as indicated in official documentation.

Voltage Reference Selection Notes

Select this part for applications requiring a stable 5V reference with low drift. The BC grade offers a balance of accuracy and cost compared to higher grades. Consider the SOIC-8 package size for PCB layout constraints. Verify that the 10mA current capability meets load requirements in both sourcing and sinking configurations.

Voltage Reference Part Context

This component belongs to the LT1236 family of precision references from Analog Devices. The family includes variants with different output voltages (5V and 10V), accuracy grades (A, B, C), and packages (SOIC, DIP). The LT1236 is designed to replace older references like the AD586 and AD587 due to pin compatibility and superior performance metrics.
