GC version LM1875 desktop amplifier

Overview

GC version 1875 power amplifier circuit

The full name of "GC" is GainClown. It is a very good-sounding LM1875 circuit that has been optimized through repeated comparisons and verifications abroad. It has a wide frequency range, is delicate, durable, and has a very stable midpoint. The principle is that the voltage at the two input terminals of the inverting amplifier circuit is always 0 and does not change with the input signal. The input voltage of the transistor at the input terminal of the amplifier is constant, the bias state always maintains the optimal operating point, and the distortion of the inverting amplifier is smaller.

The circuit is simple, with three resistors and a coupling capacitor. No debugging is required after the connection is completed, and the sound will be output directly.

Real-time solution to single chip microcomputer delay
1. If the MCU uses the delay function to delay, that is, the empty waiting method is used to delay, but the MCU has only one core and cannot split itself to handle other things. If this method is used
STM32L152 enters STOP mode, and the ADC reading value remains unchanged after WAKEUP by RTC
As the title says, using the STOP low power mode, the power consumption is reduced. The maximum time in STOP mode is about 32 seconds each time (RTC register is full), so it is cycled many times (abou
