A22H165MJ

Overview

The A22H165MJ is a Class-G stereo headphone driver designed for high audio performance and power efficiency in space-constrained applications. It features an integrated buck converter that adjusts amplifier voltage based on signal amplitude to optimize battery life. The device achieves a total current consumption of 2.1 mA at 100 μW output power with a 10 dB crest factor, while standby current is as low as 0.6 μA. It is housed in a flip-chip package measuring 1.65x1.65x0.6 mm with 16 bumps and a 0.4 mm pitch.

Feature Summary

Class-G architecture with integrated buck converter for dynamic voltage adjustment
Ultra-low standby current consumption extending battery life
High audio quality combined with high power efficiency
Compact flip-chip package suitable for space-limited designs

Applications

Smartphones
Tablets
Media players

Procurement Notes

Verify the specific suffix MJ against official STMicroelectronics documentation to confirm pinout, thermal characteristics, and packaging details. Ensure compatibility with I2C control or u-less configuration requirements as specified in the datasheet. Cross-reference the package dimensions and bump pitch with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when designing portable audio systems requiring high efficiency and minimal board space. The integrated buck converter eliminates external filtering components, simplifying the bill of materials. Consider the ultra-low standby current for devices requiring extended battery longevity in sleep modes.
