TLE2141QDRQ1

Instrumentation, Op Amps, Buffer Amps Overview

The TLE2141QDRQ1 is a single-channel precision operational amplifier from the Excalibur series, manufactured by Texas Instruments. It features a gain-bandwidth product of 5.9 MHz and a slew rate of 45 V/us. The device operates within a supply voltage range of 4 V to 44 V, with a typical quiescent current of 3.5 mA per channel. Key electrical specifications include an input offset voltage of 200 µV, an input bias current of 700 nA, and a common-mode rejection ratio of 108 dB. It supports rail-to-rail output and delivers up to 50 mA of output current per channel. The component is housed in an 8-SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High-speed performance characterized by a 45 V/us slew rate and 5.9 MHz gain-bandwidth product.
• Precision signal processing capabilities with low input offset voltage and high common-mode rejection.
• Wide single-supply operation supporting voltages up to 44 V with rail-to-rail output swing.

Instrumentation, Op Amps, Buffer Amps Applications

• Automotive sensor signal conditioning
• Industrial data acquisition systems
• Active filter circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix QDRQ1 to confirm the SOIC-8 surface-mount package and automotive grade status. Ensure the design accounts for the 4 V minimum supply voltage requirement. Confirm that the 8-SOIC footprint matches the PCB layout constraints. Validate thermal dissipation requirements based on the 3.5 mA quiescent current and load conditions during operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when automotive reliability is required alongside high-speed amplification. The wide 4 V to 44 V supply range offers flexibility compared to standard 5 V or 15 V op-amps. The 50 mA output drive capability suits direct driving of moderate loads without additional buffering. Consider the 200 µV offset voltage for precision applications where drift must be minimized.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLE2141 family of precision amplifiers. The 'Q' prefix indicates automotive qualification, while 'D' specifies the SOIC package and 'RQ1' denotes reel packaging for automated assembly. It complements other Excalibur series devices designed for robust industrial and automotive environments requiring high speed and precision.
