blood pressure meter and . Nowadays, blood glucose meter and have added voice function. Although the effect of visual communication is intuitive, the elderly with poor eyesight cannot see clearly the current blood pressure situation, so many manufacturers Will join: WTN6 voice chip + WT1312 power amplifier chip solution;
WTN6 voice chip can realize the voice prompt function, WT1312 can amplify the PWM signal and drive a higher power speaker. This time, the editor Sister Wei introduced one, from Shenzhen A PWM signal amplification chip developed by Weichuang Zhiyin: WT1312;
WT1312 is a low-cost, high-reliability PWM power amplifier chip developed by Shenzhen Weichuang Zhiyin. The maximum output power can reach 2.3W. It has built-in over-current, Short circuit protection; effectively protects the chip from damage under abnormal conditions;
function overview
