TPA5601-SC5R

Instrumentation, Op Amps, Buffer Amps Overview

The TPA5601-SC5R is a single-channel operational amplifier from the 3PEAK TPA560x series, housed in an SOT353 (SC70-5) package. It features zero-drift technology with a maximum offset voltage of ±10 μV across the −40°C to 125°C temperature range and a drift of 0.013 μV/°C. The device operates on a supply voltage of 2.5 V to 5.5 V, drawing 1.6 mA quiescent current per amplifier. Key electrical parameters include a 15 MHz gain-bandwidth product, 7 V/μs slew rate, and 10 nV/√Hz input voltage noise density at 1 kHz.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift architecture utilizing chopper stabilization for ultra-low offset voltage and minimal drift across extended temperatures.
• Rail-to-rail input and output capability allowing signal swing within 100 mV of supply rails.
• Low flicker noise performance achieved through internal notch filtering at the chopping frequency.
• High precision AC performance with 15 MHz bandwidth and fast settling time suitable for high-speed signal conditioning.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix SC5R corresponds to the SOT353 package and tape-and-reel quantity of 3000 units as listed in the official order information table. Confirm RoHS compliance and halogen-free status by checking the 'Green' designation in the manufacturer's documentation. Ensure the revision history indicates production status for this specific part number variant before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when system requirements demand sub-microvolt offset stability over wide temperature variations without external trimming. The low 1/f noise characteristic makes it suitable for DC-coupled applications where flicker noise typically degrades accuracy. Verify that the 1.6 mA quiescent current aligns with thermal constraints in the compact SOT353 package, which has a junction-to-ambient thermal resistance of 400 °C/W.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TPA560x family of zero-drift operational amplifiers manufactured by 3PEAK. The TPA5601 denotes the single-channel configuration, while the TPA5602 represents the dual-channel variant. Both share identical electrical specifications but differ in pin count and package options. The SC5R suffix specifically identifies the surface-mount SOT353 package form factor optimized for space-constrained PCB layouts.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include the TPA5601U-SC5R, which shares the SOT353 package and electrical characteristics but carries a different marking code. Verify functional equivalence regarding input bias current and common-mode rejection ratio if substituting with other zero-drift op-amps from different manufacturers.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the chopper stabilization affect the output signal?

Chopper stabilization reduces 1/f noise and offset voltage but introduces residual voltage ripple at the chopping frequency of 560 kHz. A post-filter is recommended at the output if the input signal frequency is close to this chopping frequency to prevent interference.

What is the input common-mode voltage range?

The devices feature rail-to-rail input capability, extending 100 mV beyond the supply rails. This is achieved using complementary PMOS and NMOS input differential pairs operating in parallel.
