ETK4993
ETK4993 is Fully differential audio power amplifier manufactured by Etek Microelectronics.
General Description The ETK4993 is a fully differential audio power amplifier designed for portable munication 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 ponents and lowpower shutdown mode make ETK4993 ideal for wireless handsets. The ETK4993 is unitygain stable, and the gain can be configured by external r...
