BA5406 Features
Small "pop" noise. Good low voltage characteristics. Begins operating VCC = 5V (Typ.). Good channel balance. Good distortion characteristics (THD = 0.3% when PO = 0.5W). Easy-to-mount 12-pin SIP-M package that requires little PCB space. The ripple filter pin (pin 6) can be used for muting (by setting it to ground potential). Symmetrical pin assignments simplifies PCB artwork. Package has low thermal resistance to simplify heatsink design. Built-in treble phase compensation capacitors. Low radio-band noise generated. Can be freely positioned in the set.
BA5406 Typical Application
Stereo radio cassette players, stereo component systems, and TVs.
