TPA6584-SO2R

Instrumentation, Op Amps, Buffer Amps Overview

The TPA6584-SO2R is a quad-channel, low-power CMOS operational amplifier from the TPA658x series. It features rail-to-rail input and output capabilities with a supply voltage range of 2.7 V to 5.5 V. Key electrical specifications include a gain-bandwidth product of 10 MHz, a slew rate of 8 V/μs, and a quiescent current of 1.2 mA per channel. The device exhibits low offset voltage (±1.5 mV max) and low 1/f noise (10 nV/√Hz at 1 kHz). It operates within a temperature range of −40°C to 125°C and includes protection against output glitches during power transitions.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix SO2R corresponds to the SOP-14 package configuration as documented in the manufacturer's order information table. Confirm that the component status remains active for production use by checking the latest datasheet revision history. Ensure compatibility with the required operating temperature range and supply voltage constraints before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring multiple channels in a single package with low power constraints. The quad configuration is suitable for systems needing four independent amplifiers. Consider the 10 MHz bandwidth and 8 V/μs slew rate for general-purpose signal conditioning. The rail-to-rail I/O makes it appropriate for single-supply designs where maximizing dynamic range is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

The TPA6584-SO2R belongs to the TPA658x family of low-cost, low-noise CMOS RRIO op-amps manufactured by 3PEAK. This series includes single (TPA6581), dual (TPA6582), and quad (TPA6584) variants. The TPA6584 specifically provides four amplifiers in one package, utilizing proprietary design techniques for high-performance AC characteristics while maintaining low power consumption.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Verify pinout compatibility and electrical parameters against alternative quad op-amps if cross-referencing is necessary. The SO2R suffix indicates the SOP-14 package; ensure any replacement matches this physical footprint and thermal requirements.
