TP5552-VR

Instrumentation, Op Amps, Buffer Amps Overview

The TP5552-VR is a dual-channel chopper-stabilized zero-drift operational amplifier from the TP555x family, manufactured by 3PEAK. It operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.75 V. The device features an ultra-low input offset voltage of 5 μV (max) and a maximum offset drift of 0.05 µV/°C. It provides a gain-bandwidth product of 3.5 MHz and a slew rate of 2.5 V/μs with rail-to-rail input and output capabilities. Quiescent current consumption is 550 μA per amplifier channel. The component is housed in an MSOP-8 package and supports operation across a temperature range of -40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper-stabilized architecture eliminates flicker noise with no 1/f noise corner down to 0.1 Hz
• Rail-to-rail input and output swing maximizes dynamic range within the supply rails
• High common-mode rejection ratio and power supply rejection ratio ensure signal integrity
• Internal ESD protection diodes safeguard inputs against electrostatic discharge events

Instrumentation, Op Amps, Buffer Amps Applications

• Medical instrumentation requiring high precision
• Temperature measurement systems
• Precision current sensing circuits
• Low frequency ADC drivers demanding low drift
• Process control systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix matches the required package type, as the VR suffix indicates the MSOP-8 variant. Confirm that the tape and reel quantity aligns with production needs, as standard packaging quantities vary by package style. Ensure the design accounts for the specified moisture sensitivity level during storage and assembly processes to maintain component reliability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when applications require near-zero drift performance without the complexity of external calibration. The dual-channel configuration offers space efficiency compared to using two single amplifiers. Consider the 3.5 MHz bandwidth sufficient for most low-frequency precision tasks while maintaining low power consumption relative to higher-speed alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

The TP5552-VR belongs to the TP555x series of ultra-low noise, zero-drift operational amplifiers. This family includes single (TP5551), dual (TP5552), and quad (TP5554) versions. All variants share identical electrical characteristics regarding offset voltage, noise, and bandwidth, differing only in the number of channels integrated into the silicon die and their respective physical package options.
