Product Description
Overview
NVA series voice chip is an industrial-grade OTP voice chip suitable for factory mass production. It has many significant advantages such as low cost, stable performance, high sound quality, convenient control, and simple circuit. The launch of NVA is similar to the current mask price in the industry, but there is no minimum limit, which makes up for a shortcoming in the current industry. NVA is a stable-performance voice chip that does not require any peripheral circuits and can work normally in extremely harsh noise environments. It has a wide temperature and voltage range, and the normal operating range is as wide as 1.8V to 5.5V, which makes up The current anti-interference ability of voice chips on the market is poor. The NVA series voice chip has a set of PWM output ports, which can directly push 0.5w speakers with clear sound quality. Built-in LVR reset, no additional reset circuit required. Built-in accurate internal resistance frequency vibrator (maximum error of only + -1%), no external resistor required. An obvious advantage of NVA is that the OTP programming program can be seamlessly connected with the MASK mask. That is to say, users can trial production OTP in the early stage of trial production. When trial production enters large-scale production, they can directly press OTP samples. MASK masks are put into production to reduce costs, and customers do not need to confirm samples again. The NVA series voice chip has multiple key trigger methods, and can output various forms of level signals, which can be set to change according to the ups and downs of the voice. In addition, NVA supports the main control MCU's first-line serial port control, which can control multiple voice triggers at will. The NVA series voice chip has a variety of practical packaging forms: DIP8, DIP14, SOP8, SOP14, etc., the peripheral circuit only needs a power supply coupling capacitor, stable work, wide operating voltage, ultra-low standby power consumption and wide temperature Performance makes the NVA series voice chip have first-class cost-effective advantages in a wide range of applications.

|
Vreg
|
regulates the power supply
|
When the working voltage exceeds 4.5V, a 0.1UF capacitor needs to be connected to the ground. If it is less than 4.5V, it can be left floating.
