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.
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.
