TL4051BQDCKT

Overview

The TL4051BQDCKT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It features an adjustable output voltage range from 1.225V to 10V, selected via external resistors. The device offers a maximum initial accuracy of ±0.2% and a temperature coefficient of 50ppm/°C. It operates within an extended industrial temperature range of -40°C to 125°C. The component is housed in a compact SC-70-5 surface-mount package.

Feature Summary

• Provides stable reference voltage with low dynamic impedance and noise
• Capable of operation across a wide current range without requiring output capacitors
• Delivers high precision through tight initial tolerance specifications

Applications

• Data acquisition systems
• Power supply monitoring circuits
• Precision audio equipment
• Battery-powered devices

Procurement Notes

Verify the specific suffix 'Q' indicates the extended temperature grade (-40°C to 125°C) and 'B' denotes the ±0.2% accuracy class. Confirm the 'DCKT' suffix corresponds to the SC-70-5 package and tape-and-reel packaging format. Ensure compatibility with system thermal requirements and input voltage limits before integration.

Selection Notes

Select this component when precise voltage referencing is required in space-constrained designs. The adjustable output allows flexibility for various reference levels. Consider the extended temperature rating for harsh environments. Evaluate power consumption against battery life requirements due to its micropower characteristics.

Part Context

This part belongs to the TL4051 family of micropower shunt voltage references. It complements fixed-output variants like the TL4051A12 series. The family provides options for different accuracy grades and temperature ranges, supporting diverse industrial and automotive applications requiring reliable voltage standards.

Replacement Considerations

Compatible substitutes include other TL4051 variants with matching accuracy and temperature ratings. Verify pinout compatibility for direct replacement. Check if alternative packages require layout modifications. Ensure equivalent noise performance and load regulation specs meet circuit requirements.
