5W BTL Audio Power Amplifier http://onsemi.
com 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 cause muddiness in the audio output, has been significantly reduced by both circuit and wiring pattern improvements.
Thus this amplifier can provide powerful lows and clear highs.
Note that this device is pin compatible with the 20W×2-channel LA4628, and allows end products differentiated by their power rating to share the same printed circuit board.

5W (at VCC = 12V, RL = 4Ω, THD = 10%) • PMPO reference data : 115W×2 (VCC = 20V, RL = 4Ω) • High-fidelity design (fL < 10Hz, fH = 130kHz) • Extremely low impulse noise levels • An arbitrary amplifier startup time can be set up with external components.
• Full complement of built-in protection circuits (includes circuits that protect against shorting to VCC, shorting to ground, load shorting, overvoltages and excessive temperatures) Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Maximum output current Allowable power dissipation Operating temperature Storage temperature Symbol VCC max IO peak Pd max Topr Tstg Conditions No signal Per channel With an arbitrarily large heat sink Ratings 24 3.
