blood oximeter is an electronic instrument for measuring blood sugar levels. For most diabetic patients, the blood glucose meter can accurately measure blood sugar. After the instrument detects the results, the value can be viewed. The LCD display and voice broadcast tell the user the current blood sugar situation; as a convenient electronic product, the
blood glucose meter will embed a voice chip as the sound source, and add a pwm audio amplifier chip to increase the sound size, which is convenient Elderly people with poor vision can hear the current blood sugar status clearly;
Shenzhen Weichuangzhiyin has developed a low-cost PWM audio power amplifier chip: WT1312. The maximum output power can support a 2.3W power amplifier circuit and ultra-low standby power consumption ( Quiescent current is less than 3uA), and the small package form (SOT23-6) allows the PCB board to free up more development space;
WT1312 Features
(1) Working voltage: 1.8V~6V
(2) In standby mode, static The current is less than 3uA
(3) Package form: SOT23-6
(4) Maximum output power 2.3W (5V/4ohm/STP23-6)
