TP1281L1-TR

Instrumentation, Op Amps, Buffer Amps Overview

The TP1281L1-TR is a single-channel operational amplifier from the TP128x series, manufactured by 3PEAK. It operates within a supply voltage range of 4.5 V to 36 V and features rail-to-rail output capability with input common-mode voltage extending to the negative supply rail. Key electrical specifications include a gain-bandwidth product of 7 MHz, a slew rate of 20 V/μs, and a maximum offset voltage of ±150 μV. The device draws a quiescent current of approximately 1.5 mA at 30 V and includes over-temperature protection that triggers at 170°C. It offers high electromagnetic interference rejection of 45 dB at 1 GHz and robust ESD protection ratings.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix matches the required package type, as the TP1281L1-TR designation corresponds to the SOT23-5 package configuration. Confirm the tape and reel parameters align with automated assembly requirements. Ensure the component source is traced to authorized distribution channels to guarantee authenticity and adherence to the manufacturer's quality standards for industrial-grade reliability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high supply voltage operation up to 36 V is required alongside low power consumption. The rail-to-rail I/O characteristics make it suitable for single-supply applications where maximizing dynamic range is critical. Consider the 7 MHz bandwidth and 20 V/μs slew rate for general-purpose signal processing tasks requiring moderate speed. The integrated thermal shutdown provides an additional layer of reliability in high-stress operating conditions compared to standard amplifiers lacking such protection.

Instrumentation, Op Amps, Buffer Amps Part Context

The TP1281L1-TR belongs to the TP128x family of high supply voltage operational amplifiers designed by 3PEAK. This series utilizes proprietary design techniques to achieve stable high-frequency response and low distortion while maintaining low quiescent current. The family includes single, dual, and quad channel variants, allowing designers to scale channel count without changing core electrical characteristics or pinout compatibility across different package options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet indicates the TP128x series can serve as plug-in replacements for commercially available op amps to reduce power and extend input/output range. Specific cross-reference part numbers are not provided in the official documentation; engineers should verify pin compatibility and electrical parameter margins against existing designs before substitution.
