NVB series voice chip is a newly launched industrial -grade OTP voice chip suitable for factory mass production types. It has many significant advantages such as low cost, stable performance, high sound quality, convenient control, and simple circuits. NVB is a stable voice chip. Without any peripheral circuit, it can work normally in a extremely harsh noise environment. It has a wide range of temperature resistance and voltage resistance. The normal working range is 1.8V ~ 4.5V, which makes up for it to make up At present, the disadvantage of poor anti -interference capabilities on the market.
