Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the B grade designation corresponds to the required 0.1% accuracy and 20ppm/°C drift specifications for your application. Ensure the industrial temperature range of –40°C to 85°C meets environmental requirements. Check for RoHS compliance status on the official datasheet before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a 5V reference is needed with moderate precision (0.1%) and low power consumption. The B grade offers a balance between cost and performance compared to the higher precision A grade. Consider the TSOT-23 package size constraints and the requirement for a minimum 1µF output capacitor for stable operation. Verify that the 20ppm/°C temperature drift fits within system error budgets.

Voltage Reference Part Context

This component belongs to the LT6656 family of 1µA precision series voltage references. The family includes options for various output voltages and packages such as DFN and LS8. The IS6 suffix denotes the Industrial temperature grade (-40°C to 85°C) and the S6 package type (TSOT-23). The B grade specifies the electrical tolerance class for this specific variant.
