TL4050B41IDBZR

Overview

The TL4050B41IDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096V with an initial accuracy tolerance of ±0.2%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 50ppm/°C. Key electrical characteristics include a cathode current of 73 µA, a maximum output current of 15 mA, and a noise level of 93µVrms measured between 10Hz and 10kHz. It is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances for sensitive analog circuits.
• Operates with extremely low quiescent current consumption suitable for battery-powered applications.
• Maintains stable reference performance across industrial temperature ranges with minimal drift.

Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement systems
• Data acquisition channels

Procurement Notes

Verify the specific suffix IDBZR corresponds to the SOT-23-3 tape-and-reel packaging configuration. Confirm that the B-grade accuracy class meets the design requirements for initial voltage tolerance. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits to maintain guaranteed performance specifications.

Selection Notes

Select this component when a fixed 4.096V reference is required with superior accuracy compared to standard zener diodes. The low power consumption makes it ideal for energy-constrained designs. Consider the SOT-23-3 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability for surface-mount assembly processes.

Part Context

This part belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades (A, B, C) packaged in small form factors like SOT-23 and SC-70. These devices are designed to replace bulkier or less accurate reference solutions in modern compact electronic equipment.
