The ETK4992 is a fully differential audio power amplifier designed for portable communication device applications.

It is capable of delivering 1.25 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V battery voltage.

It operates from 2.2 to 5.5V.

Etek Microelectronics ETK4992 1.25 Watt Fully Differential Audio Power Amplifier.

like 90dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving 8-bump WLCSP package, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make ETK4992 ideal for wireless handsets. The ETK4992 is unity-gain stable, and the gain can be configured by external resistors.
