It delivers an 11 MHz gain-bandwidth product and a 20 V/µs slew rate. ## Key ratings and what they mean for a field swap or BOM line The 20 V/µs slew rate and 11 MHz GBW suit audio-band signals. The quad draws 1.8 mA per channel. That means a field-service tech needs a fine-tip iron or hot-air station, and a steady hand — this is not a socketed DIP you can swap in a parking lot. There is no NRND or EOL notice, so it is safe to qualify into a new BOM or specify as a spare.","metaTitle":"OPA1644AIPW SoundPlus™ Audio Op-Amp, 11 MHz, 20 V/µs, Quad","metaDescription":"TI OPA1644AIPW quad audio op-amp, 11 MHz GBW, 20 V/µs slew rate, rail-to-rail output, 4.5–36 V supply, -40 to 85°C.
