TPA6552-SO1R

Instrumentation, Op Amps, Buffer Amps Overview

The TPA6552-SO1R is a dual-channel rail-to-rail input/output operational amplifier from the TPA655x series. It operates on a single supply of 2.5 V to 5.5 V or split supplies of ±1.25 V to ±2.75 V. Key electrical parameters include a gain-bandwidth product of 10 MHz, a slew rate of 3 V/μs, and a maximum offset voltage of ±1.5 mV at 25°C. The device features low noise with 10 nV/√Hz at 1 kHz and 20 nV/√Hz at 10 Hz. Quiescent current per channel is typically 1 mA, with a maximum of 1.2 mA across the operating temperature range of −40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package marking and date code against the SOP8 tape and reel specifications provided in the official datasheet. Confirm that the ordering suffix matches the required packaging format. Ensure compatibility with standard surface-mount assembly processes for the specified thermal resistance values.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel amplification with rail-to-rail I/O is required within a 5.5 V supply limit. The low noise density makes it suitable for sensitive sensor interfaces. Consider the TPA6551N variant if a shutdown function is needed, as the standard TPA6552 lacks this feature. Verify load conditions to ensure output swing meets system requirements near the supply rails.
