TH040 Trigger Voice Combination Example

Voice File	Description
Voice File A	Hello ( 1.5”)
Voice File B	Good Morning (3”)
Voice File C	John (1”)
Voice File D	Tom (1”)
Voice File E	Mary (1.5”)

Group1 = Step1 + Step 2
Group 2 = Step3 + Step 4 + Step 5
Group 3 = Step 6 + Step 7

Group1 = Hello John
Group 2= Hello Tom Good Morning
Group 3 = Good Morning Mary

Step1 = Voice File A
Step 2 = Voice File C
Step 3 = Voice File A
Step 4 = Voice File D
Step 5 = Voice File B
Step 6 = Voice File B
Step 7 = Voice File E

Total use 3 Group , 7 Steps
Voice duration= Hello + Good Morning + John + Tom + Mary
= 1.5” + 3” + 1” + 1” + 1.5”
= 8”
Total duration = 8” ( 20”-8” = 32” space are free , can add more Voice File )

產品優勢：

1, Otp-TF040 內置電阻、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省30%－50% .

2, 工作電壓2.4V—5.5V；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語音芯片產品,不需光罩費,音質和單價市場最優.

出貨形式：

dip、 SOP、COB（可為積壓盒專用）、裸片（已燒錄好）。 其中裸片一塊Wafer可以同時燒錄4款不同的產品，直接綁定生產，大大地節約生產時間, dip、 SOP、COB 1天交貨，裸片5-7天交貨。
