12V Dual Power Amplifier BA5406 Dimensions (Unit: mm) The BA5406 is a monolithic dual OTL power amplifier containing two sets of high-power AF power amplifiers. The device delivers 5 watts x 2 into 30 loads with a 12V supply, or 2.8 watts x 2 into 30 loads with a 9V supply. The BA5406 features minimal power-on pop noise and immunity to supply voltage drop. With its minimal RF radiation, the device is ideally suited for use in stereo radio cassette recorders. m.Jmmmlmlmlmfmlmlmmlia 1 2 3 4 5 6 7 8 9 10 11 12 Fig. 1 Block Diagram Features 1. Minimal power-on pop noise. 2. Immunity to supply voltage drop (operates down to Vcc=45V typ.). 3. Excellent channel balance. 4. L o w d i s t o r t i o n (THD=0.3% at PO=O.5W). 5. 12.pin SIP package for mounting ease and saved space on a PC board. 6. Ripple filter input (pin 6) can also be used as a muting control input. 7. Symmetrical pin configuration facilitates art work. 8. Low thermal resistance of the package makes heat-sink design easy. 9. Built-in high-frequency phase compensation capacitor. IO. Minimal RF radiation allows for free system layout.
