... Ordering number : ENN6631 Overview The LA4625 is a 2-channel general-purpose BTL audio power amplifier provided in a miniature package. It was designed for the best possible audio quality and features an extended low band roll-off frequency provided by a newly-developed NF circuit that does not require an external capacitor. Furthermore, crosstalk, which can ...

... V 5.21 V External Components C1 and C4: Input capacitors. A value of 2.2 µF is recommended. Determine the polarity based on the DC potential of the circuit connected directly to the LA4625 front end. Note that the low band response can be adjusted by varying f with the capacitors C1 and C4. L C2: Decoupling capacitor (ripple filter) C3: Sets the amplifier starting time, which will be approximately 0.6 seconds for a value of 33 µ ...

... Impulse noise improvements • While the LA4625 achieves a low level of impulse noise, if even further reductions in impulse noise at power on/off (and when switching into or out of standby mode) a 0.47 µF capacitor may be inserted between pin 7 and the PRE GND pin (pin 3). (Pin 7 is the output amplifier bias pin. Since the ability to withstand shorting the output pins to ...
