LA4625
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.
Features
Total output : 13.5W+13.5W (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)
