TL4050B41IDCKT

Overview

The TL4050B41IDCKT is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.2%. The device features a temperature coefficient of 50 ppm/°C and supports a maximum cathode current of 15 mA. It operates within a junction temperature range of -40°C to +125°C and is housed in a SC-70-5 surface-mount package.

Feature Summary

• Delivers high precision voltage regulation with ±0.2% initial accuracy for stable reference applications.
• Designed for low power consumption, suitable for battery-operated systems requiring minimal quiescent current.
• Offers wide operating temperature stability across industrial ranges with a consistent 50 ppm/°C temperature coefficient.

Applications

• Portable instrumentation requiring precise analog-to-digital conversion references
• Battery-powered measurement devices needing long-term stability
• Industrial control systems utilizing serial communications interfaces

Procurement Notes

Verify the specific suffix IDCKT confirms the SC-70-5 package and tape-and-reel delivery format. Confirm that the B grade designation matches the required ±0.2% accuracy specification for your design. Ensure compatibility with the 4.096V output requirement and check for any RoHS compliance documentation relevant to your region's regulations before finalizing procurement.

Selection Notes

Select this component when a compact SC-70-5 footprint is necessary alongside high precision requirements. The 4.096V output is ideal for interfacing directly with ADCs that utilize standard reference levels. Consider the 15mA current limit when designing the series resistor to ensure adequate headroom without exceeding power dissipation limits in the small package.

Part Context

This part belongs to the TL4050 family of micropower shunt voltage references from Texas Instruments. The family offers various accuracy grades (A, B, C) and output voltages. The TL4050B41IDCKT specifically targets applications demanding tighter tolerance than standard references while maintaining low power operation in a miniature surface-mount form factor.

Replacement Considerations

TL4050B41IDCKRG4 is a verified equivalent variant within the same product line offering identical electrical specifications and pinout configuration.
