General Description

The ETK4993 is a fully differential audio power amplifier designed for portable communication device applications. It is capable of delivering 1.7 watt of continuous average power to an 8Ω BTL load , 2.5 watt of continuous average power to an 4Ω BTL load with less than 1% distortion (THD+N) from a 5V battery voltage. It operates from 2.2 to 5.5V.

Key Features

like 90dB PSRR at 217Hz, improved RFrectification immunity, the spacesaving DFN8, MSOP8 package, the advanced pop & click circuitry, a minimal count of external components and lowpower shutdown mode make ETK4993 ideal for wireless handsets. The ETK4993 is unitygain stable, and the gain can be configured by external resistors. Features Fully differential amplifier Improved PSRR at 217Hz (VDD>3.0V) 90dB (typ) Ultra low shutdown current 0.01μA (typ) Improved pop & cl.
