TP2124-TR

Instrumentation, Op Amps, Buffer Amps Overview

The TP2124-TR is a quad ultra-low-power, precision CMOS operational amplifier from 3PEAK. It features a maximum supply current of 950 nA per amplifier and an ultra-low typical input bias current of 1 pA. The device offers a gain-bandwidth product of 18 kHz with a slew rate of 10 mV/μs. Input offset voltage is trimmed to below 1.5 mV with a temperature drift of 0.5 μV/°C. It operates on single supplies from 1.8 V to 6.0 V or dual supplies from ±0.9 V to ±3.0 V. The output swings rail-to-rail, sourcing and sinking 20 mA, and it remains stable driving capacitive loads up to 1,000 nF.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Ultra-low power consumption with 600 nA quiescent current per channel
• Precision analog trim for low offset voltage and minimal temperature drift
• Rail-to-rail input and output capabilities extending beyond supply rails
• High ESD protection rating of 6 kV HBM and 1.5 kV CDM

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered devices and energy scavenging sensor networks
• Current sensing in mobile accessories and backup battery systems
• Buffering high-impedance chemical sensors such as pH probes
• Low-power filters and threshold detectors/discriminators

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package variant (SOP14) associated with the -TR suffix against the manufacturer's official ordering information. Confirm that the tape and reel dimensions match your automated assembly equipment requirements. Ensure the operating environment stays within the specified -40°C to 125°C range to maintain the guaranteed electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when system design requires minimizing quiescent current while maintaining precision signal conditioning. The wide common-mode input range allows for true ground sensing in single-supply applications. Consider the 18 kHz bandwidth limit; it is suitable for low-frequency sensor interfaces but not for high-speed data acquisition.
