ETK4993 - Fully differential audio power amplifier

General Description

The ETK4993 is a fully differential audio power amplifier designed for portable communication device applications.

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.

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.   Features Fully differential amplifier Improved PSRR at 217Hz (VDD>3.
