TPA3662-VS1R

Instrumentation, Op Amps, Buffer Amps Overview

The TPA3662-VS1R is a dual-channel CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply of 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V. Key electrical specifications include a gain-bandwidth product of 2.5 MHz, a slew rate of 2 V/μs, and a maximum offset voltage of ±250 μV at 25°C with a drift of 2 μV/°C. The quiescent current per channel is 0.8 mA. The device provides a minimum common-mode rejection ratio of 100 dB across the full common-mode range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package marking information (A3662) and moisture sensitivity level (MSL 3) against your assembly requirements. Confirm that the tape and reel quantity matches your production needs. Ensure compatibility with RoHS and halogen-free standards as defined by the manufacturer's green product policy before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel solution with rail-to-rail I/O and low offset voltage is required. It is suitable for applications demanding high common-mode rejection without crossover distortion. Consider the MSOP8 package constraints regarding thermal dissipation and board space compared to SOP8 alternatives within the same family.

Instrumentation, Op Amps, Buffer Amps Part Context

The TPA3662-VS1R belongs to the TPA366x series of operational amplifiers manufactured by 3PEAK. This series includes single (TPA3661), dual (TPA3662), and quad (TPA3664) variants sharing identical electrical characteristics but differing in channel count and pin configurations. The VS1R suffix indicates the MSOP8 package type.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional replacements within the same family include TPA3662-SO1R (SOP8 package). Other variants like TPA3661 or TPA3664 offer different channel counts but share the same core electrical specifications and pinout logic for individual channels.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the zero-crossover feature benefit signal integrity?

The zero-crossover input topology eliminates the input offset transition region found in standard complementary input stages, ensuring no crossover distortion and maintaining excellent CMRR across the entire common-mode input range.

What is the common-mode input voltage range?

The common-mode input voltage range extends from slightly below the negative supply rail to slightly above the positive supply rail, specifically (−VS) − 0.1 V to (+VS) + 0.1 V.
