Monaural Class-D Speaker Amplifier
BD5465GUL
No.10101EAT05
●Description
BD5465GUL 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 output limit level uses a control type which doesn’t follow up power supply.
The time until the limit release operation of output level is called the release time (or recovery time). This IC adopts release
time (560ms/1dB Typ.) and suits the applications which play music.
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 it’s also suitable in repeating active and shutdown.
●Feature
1) Contains Digital ALC (Automatic Level Control) Function
2) External Parts: 3 points
3) Ultra slim type package: 9pin WL-CSP (1.8×1.8×0.55mmMax.)
4) BD5460 / 61GUL (No ALC Function, Gain Fixed Goods) Pin Compatible Specs
BD5466 / 67 / 68GUL (ALC Function, Gain Fixed Goods) Pin Compatible Specs
5) Maximum Gain: 12 dB (Typ.) [during ALC operation, +12～-3dB@1dB Step]
6) ALC limit level control type : Fixed type doesn’t follow up power supply
7) Limit output power: 0.6W (Typ.) [VDD=3.4～5.5V, RL=8Ω]
8) ALC release (recovery) time: 560ms/1dB (Typ.)
9) Audio Analog Input (corresponds to single-end input / differential input)
10 Output LC filter free
11) Pop noise suppression circuit
12) Shutdown Function (use as mute at the same time) [low shutdown current = 0.01μA (Typ.)]
13) Contains protection circuit: output short, thermal shutdown, under voltage lockout (UVLO)
●Applications
Mobile phone, Portable audio device, PND, DSC, Note-PC etc.
