Audio Amplifiers Procurement Notes

Verify that the ordering suffix matches the specific package type required for your design. Confirm the gain variant corresponds to the application needs. Ensure compliance with RoHS standards as indicated by the NOPB designation. Check the latest datasheet revision for any updates to electrical characteristics or mechanical dimensions before finalizing the bill of materials.

Audio Amplifiers Selection Notes

Select this part when a higher gain than standard JFET microphones is required without adding external components. The 23.8 dB gain makes it suitable for low-output transducers. Consider the 4-bump DSBGA package constraints for PCB layout. Verify that the operating temperature range meets the environmental requirements of the target device.
