TPH2502-SR

Overview

The TPH2502-SR is a dual-channel, high-speed, unity-gain stable CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 2.5 V to 5.5 V with a quiescent current of 6.5 mA per amplifier. Key electrical specifications include a gain-bandwidth product of 120 MHz, a slew rate of 180 V/μs, and an input offset voltage of 2 mV maximum. The device delivers an output current exceeding 100 mA and incorporates thermal shutdown protection.

Feature Summary

• Unity-gain stability with high bandwidth and fast slew rate for precision signal processing
• Rail-to-rail input and output stages maximize dynamic range in low-voltage systems
• Low input bias current and low noise density ensure high signal integrity
• Integrated thermal shutdown protects the device from overheating during fault conditions

Applications

• Low-voltage, high-frequency signal processing
• Video processing and line driving
• Optical networking and tunable lasers
• Photodiode trans-impedance amplifiers
• Fast current-sensing amplifiers

Procurement Notes

Verify the specific package variant, as the TPH2502 series is available in SOP8 and MSOP8 configurations. Confirm that the ordering suffix corresponds to the desired tape and reel format. Ensure the design accounts for the power-on requirements to maintain calibration block functionality. Validate component suitability for the target operating temperature range before finalizing procurement.

Selection Notes

Select this component for applications requiring high-speed performance with low power consumption. The dual-channel configuration is suitable for differential signaling or stereo audio paths. Consider the rail-to-rail I/O capability when designing for single-supply systems near the voltage limits. Evaluate the thermal management requirements if continuous output currents approach the maximum ratings.

Part Context

The TPH2502-SR belongs to the TPH250x family of precision, high-speed operational amplifiers manufactured by 3PEAK. This series includes single (TPH2501), dual (TPH2502), and quad (TPH2504) channel variants. The family is designed to replace commercially available op amps while offering improved power efficiency and extended input/output voltage ranges.

Replacement Considerations

The TPH2501, TPH2503, and TPH2504 are part numbers within the same functional family but differ in channel count and package options. Direct pin-compatible replacements may exist among other manufacturers' high-speed RRIO op amps, but specific substitute part numbers require verification against the official datasheet.
