E-TDA7391PDTR - Brand New STMicroelectronics Audio Amplifiers
-
Description
The E-TDA7391PDTR is a bridge class AB audio power amplifier specifically designed for high power applications in car radios. With a rated power output of 40W/3.2Ω EIAJ, 32W/3.2Ω at VS=14.4V, f=1kHz, d=10%, and 26W/4Ω at VS=14.4V, f=1kHz, d=10%. It is equipped with differential inputs that can accept either single ended or differential input signals. It has a minimum external component count with internally fixed gain (30 dB) with no bootstrap capacitors, no Boucherot cells, and no SVR capacitor. The device comes with a standby function that is CMOS compatible, programmable turn-on/off delay, and no audible pop during mute and standby operations, making it the ideal amplifier for car audio systems.
