TPA5562-VS1R

Instrumentation, Op Amps, Buffer Amps Overview

The TPA5562-VS1R is a dual zero-drift operational amplifier manufactured by 3PEAK, housed in an MSOP8 package. It operates on a supply voltage of 2.7 V to 5.5 V with a quiescent current of 0.5 mA per channel. The device features a maximum offset voltage of ±20 μV across the -40°C to 125°C temperature range and a drift of 0.01 μV/°C. Key performance metrics include a 3.5 MHz gain-bandwidth product, a 4.7 V/μs slew rate, and a low input voltage noise density of 12 nV/√Hz at 1 kHz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix VS1R corresponds to the MSOP8 package and tape-and-reel quantity of 3000 units as defined in the manufacturer's order information table. Confirm RoHS compliance and halogen-free status requirements against project specifications before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits requiring high DC accuracy combined with moderate speed. The zero-drift architecture makes it suitable for applications sensitive to temperature-induced offset variations. Ensure the power supply voltage remains within the 2.7 V to 5.5 V range to maintain specified electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TPA556x series of 5-V zero-drift operational amplifiers from 3PEAK. The series includes single-channel variants like the TPA5561 and dual-channel versions such as the TPA5562. These devices are engineered for general-purpose high-accuracy analog signal processing tasks where stability over temperature is critical.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include TPA5562-SO1R (SOP8) and TPA5562-TS1R (TSSOP8). Verify that alternative packages meet the thermal resistance and physical footprint constraints of the existing design layout.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the device handle flicker noise?

The TPA5562 uses chopper-stabilized technology to significantly reduce 1/f noise, resulting in lower noise levels at DC and low frequencies compared to standard amplifiers.

What is the recommended approach to suppress residual ripple?

A post-filter should be placed at the output of the amplifier to suppress noise at the chopping frequency and its harmonics, which may interfere with input signals close to 450 kHz.
