What is an 8-pin voice chip?

8-pin voice chip, as the name suggests, refers to a voice chip with 8 pins and encapsulated as DIP8 or sop8! This type of packaging chip is widely loved and applied by people because of its small circuit volume, convenient application and low price. Generally, enterprises and users choose this type of OTP voice chip as the first choice.

Of course, in the conventional voice chip packaging, in addition to the 8-pin voice chip, we also have 14 pin, 16 pin and 24 pin encapsulated voice chips. The function size of each different pin is slightly different. Generally speaking, the price of OTP voice chips with more "feet" will be relatively expensive.

What are the 8-pin voice chips commonly used in the industry? For what purpose? For the selection of voice chip, in addition to the pin, the price and voice length should also be considered. Different models can be selected for different industry application fields. The common eight pin voice chips include NVA, NVB, NVC, NVD series, etc,

The common 8-pin voice chip can be used in almost all places that need low cost but do not change the voice. The applications include cars (anti-theft alarm, reversing radar, GPS navigator, electronic dog and central lock); Smart home system, alarm clock, reminder; Special alarm, home anti-theft alarm; Medical instruments, vocal prompt and therapeutic instrument; Household appliances (induction cooker, rice cooker, microwave oven); Entertainment equipment (game machine, amusement machine); Learning model (early education machine, children's audio books); Intelligent transportation equipment (toll station, parking lot); Communication equipment (telephone exchange, telephone set); Children's toys in the field of industrial control (elevator, industrial equipment).

In fact, in addition to the 8-pin package pins, voice IC also has voice chips packaged as 16 pins, 18 pins (dip18), 20 pins (ssop20), 32 pins (lqfp32) and 48 pins. For example, NVA series voice chips have 8 pins, 14 pins, etc.

Of course, what type of OPT voice chip to choose is mainly determined by the function of the product. If the function is complex, we will choose a "good" voice chip to burn; If the cost budget is limited, we will trigger the real time and strive to control the cost of expenditure in line with product demand. All engineers has the final say.
