Abstract

The invention discloses a four-path analog quantity output circuit module for an electronic guitar. The module comprises a system chip, a power source circuit, a radio module circuit, a clock circuit, a reset circuit, an alarm circuit, an LED indicating lamp circuit, an OLED display circuit, a BOOT circuit, a switching circuit, a four-path analog quantity output circuit, and a USB-to-serial port circuit; the radio module circuit, the clock circuit, the reset circuit, the alarm circuit, the OLED display circuit, the BOOT circuit, the switching circuit, the four-path analog quantity output circuit and the USB-to-serial port circuit are in divergent connection with the system chip as the center; the LED indicating light circuit is connected with +3.3 V voltage; according to the power source circuit, 5V voltage is adopted, and the 5V is subjected to voltage stabilization and filtering, so that+5V voltage and 3.3 V voltage are obtained. The analog quantity output circuit redundancy technology is adopted, the resolution of an A/D conversion chip is improved, the problems that an existing circuit is complex in structure, high in instability, large in output signal interference and the like are solved, and the module has a bright market prospect.

Description

technical field [0001] The invention relates to the field of analog quantity output control, in particular to a 4-way analog quantity output circuit module for an electronic guitar. Background technique [0002] In daily life, the analog signal is a very important signal, such as controller frequency conversion, electronic organ, electric guitar, light-emitting lamp, power amplifier circuit, etc., the analog output affects the scale of the electronic organ, and the A / D conversion chip in the audio equipment The higher the resolution, the clearer the sound, the higher the resolution in the luminous lamp, the clearer and more stable the light source, the higher the resolution in the power amplifier circuit, the smoother the emitted waveform, and the farther the signal propagation distance, in the existing equipment The circuit generally uses a low-resolution chip and a single output, which easily leads to unstable signal output. When reflected in the power amplifier circuit, t...
