TPA5572Q-VS1R-S

Instrumentation, Op Amps, Buffer Amps Overview

The TPA5572Q-VS1R-S is a dual-channel, zero-drift operational amplifier from the TPA557xQ series manufactured by 3PEAK. It operates on a single supply of 2.7 V to 5.5 V or a dual supply of ±1.35 V to ±2.75 V. Key electrical specifications include a maximum input offset voltage of ±45 μV and an offset drift of ±0.01 µV/°C across the -40°C to 125°C temperature range. The device features a gain-bandwidth product of 15 MHz, a slew rate of 5 V/μs, and low noise density of 10 nV/√Hz at 1 kHz. It draws 1 mA quiescent current per amplifier and supports rail-to-rail input and output capabilities.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package marking '5572Q' and MSL Level 1 status against the official datasheet revision history. Confirm that the VS1R suffix corresponds to the MSOP8 tape and reel configuration. Ensure compatibility with the required supply voltage range and thermal management for the MSOP8 package type before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high precision and stability are required in automotive applications without the need for external trimming. The zero-drift technology eliminates the need for chopper stabilization circuitry externally. Consider the 15 MHz bandwidth and 5 V/μs slew rate for dynamic signal processing needs. Verify that the dual-channel configuration fits the board space constraints compared to single-channel alternatives like the TPA5571Q.

Instrumentation, Op Amps, Buffer Amps Part Context

The TPA5572Q-VS1R-S belongs to the TPA557xQ family of precision amplifiers designed specifically for automotive grade requirements. It serves as a high-performance alternative to commercial op amps, offering improved AC performance and stability. The part integrates proprietary design techniques to maintain low distortion and high gain while maintaining low power consumption suitable for battery-operated or efficiency-critical vehicle subsystems.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet indicates the device can serve as a plug-in replacement for commercially available op amps to improve performance. However, specific cross-reference part numbers are not provided in the source material. Designers should verify pinout compatibility and electrical parameter margins when substituting legacy components.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the TPA5572Q-VS1R-S include a shutdown function?

No, the shutdown function is only available in the TPA557xNQ variants (e.g., TPA5571NQ). The standard TPA5572Q does not feature a shutdown pin.

What is the recommended filtering for residual ripple?

Due to the internal chopping technique, a higher noise spectrum exists at the chopping frequency (400 kHz). It is recommended to place a post-filter at the output if the input signal frequency is close to the chopping frequency.
