OTP20秒-AC8020 OTP語音芯片 產(chǎn)品資料
產(chǎn)品描述: 已停產(chǎn)
AC8020是一顆支持PWM和DAC輸出的20秒的OTP語音芯片,音質(zhì)效果好,共有四個I/O口,其中1個Input,3個簡單I/O,簡單I/O只能觸發(fā)單段語音或用于馬達和閃燈,外圍僅需一顆104電容,產(chǎn)品方案成本極低.
AC8020已經(jīng)被新款OTPG-AC9020所替代,請查看AC9020最新資料.

產(chǎn)品優(yōu)勢:半 AT 導 Chip 體
1,
Otp-AC8020 內(nèi)置電阻、外圍沒有元器件,外圍電路只需要要104電容.
整個方案的費用給您節(jié)省30%-50% .
2, 工作電壓2.4V—3.6V;輸出方式:PWM&DAC .(應用于5V方案時,需要加LDO降壓芯片)
3, 當今市場唯一一款8Pin的DIP,SOP封裝OTP語音芯片.AT@CHIP
4, 唯一一款可以燒錄裸片出貨的OTP語音芯片產(chǎn)品,不需光罩費,音質(zhì)和單價市場最優(yōu).
5, 喇叭是8歐0.5W的,支持8歐阻值功率范圍 :0.25W-1W的喇叭.
6, DAC輸出時470歐1/2W的電阻接在8050的輸入腳和VSS腳.
