Monaural Class-D Speaker Amplifier
BD5468GUL
No.10101EAT08
Description
BD5468GUL is a monaural Class-D speaker amplifier that contained ALC function for mobile phone, portable type
electronic devices etc. LC filter of speaker output is not needed, can form monaural speaker amplifier. with 3 external parts.
ALC, short for Automatic Level Control, is a function that automatically adjusts up to the level of suppression of distortion
(clip) of output wave form during excessive input. The time until the limit release operation of output level is called the
release time (or recovery time). This IC adopts high-speed release time (4ms/1dB Typ.) and suits the application which
repeats big volume in the short time such as the camera shutter sound.
Through Class-D operation, efficiency is high low power consumption that is why it’s suitable for battery drive application.
The current consumption during shutdown when lowered to 0.01μA(Typ.), from the shutdown to the operation time is early
and at the same time pop sound is few that is why its also suitable in repeating active and shutdown.
Feature
1) Contains Digital ALC (Automatic Level Control) Function
2) External Parts: 3points
3) Ultra slim type package: 9pin WL-CSP(1.7×1.7×0.55mmMax.)
4) BD5460/61GUL (No ALC Function, Gain Fixed Goods) Pin Compatible Specs
BD5465/66/67GUL (ALC Function, Gain Fixed Goods) Pin Compatible Specs
5) Maximum Gain: 13dB (Typ.) [during ALC operation, 13-2dB@1dB Step]
6) ALC high speed release (recovery) time: 4ms/1dB(Typ.)
7) Limit output power : 0.7W (Typ.) [VDD=4.2V, RL=8, THD+N1%]
: 0.5W (Typ.) [VDD=3.6V, RL=8, THD+N1%]
8) Audio Analog Input (corresponds to single-end input / differential input)
9) Output LC filter free
10) Pop noise suppression circuit
11) Shutdown Function (use as mute at the same time) [low shutdown current = 0.01μA (Typ.)]
12) Contains protection circuit: output short, thermal shutdown, under voltage lockout (UVLO)
Applications
Mobile phone, Portable audio device, PND, DSC, Note-PC etc.

±1dB
The gain switch timing during ALC operation occurs at zero cross point of audio output voltage.
For that, attack time, release time will change at input frequency “fin”.
ALC Parameter is fixed. ALC operation doesn’t correspond to noise of impulse.
