Eutech Microelectronics EUA2112

The EUA2112 is a high efficiency, one channel bridged-tied load (BTL), class-D audio power amplifier. The EUA2112 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplifier. Operating from a 24V power supply, EUA2112 is capable of delivering 25W of continuous output power to a 8Ω load with 10% THD+N.

DESCRIPTION

Amplifier gain is internally configured and can be selected to 20, 26, 32 or 36dB utilizing the Go and G1 gain select pins. Advanced EMI suppression technology enables the use of inexpensive ferrite bead at the outputs while meeting EMC requirements. The speaker protection circuitry is integrated into EUA2112 to limit the amount of current through the speaker. The EUA2112 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2112 is available in thermally efficient 28-pin TSSOP package.
