BD5466GUL

●Description

BD5466GUL 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

BD5465/67/68GUL (ALC Function, Gain Fixed Goods) Pin Compatible Specs

5) Maximum Gain: 18dB(Typ.) [during ALC operation, 18～3dB@1dB Step]

6) ALC high speed release(recovery) time: 4ms/1dB(Typ.)

7) Limit output power : 0.7W (Typ.) [VDD=4.2V, RL=8Ω, THD+N≦1%]

: 0.5W (Typ.) [VDD=3.6V, RL=8Ω, THD+N≦1%]

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.
