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 )

产品优势：

1, Otp-TF040 内置电阻、外围没有元器件，外围电路只需要要104电容．

　　整个方案的费用给您节省30%－50% .

2, 工作电压2.4V—5.5V；输出方式：PWM＆DAC .(应用于5V方案时，需要加LDO降压芯片)

3, 当今市场唯一一款8Pin的DIP,SOP封装OTP语音芯片.AT@CHIP

4, 唯一一款可以烧录裸片出货的OTP语音芯片产品,不需光罩费,音质和单价市场最优.

出货形式：

dip、 SOP、COB（可为积压盒专用）、裸片（已烧录好）。 其中裸片一块Wafer可以同时烧录4款不同的产品，直接绑定生产，大大地节约生产时间, dip、 SOP、COB 1天交货，裸片5-7天交货。
