TDA1308 Silicon Microphone Amplifier Module Silicon Microphone Amplifier Microphone Head with Pre-amplification High Sensitivity

TDA1308 Silicon Microphone Amplifier Module Silicon Microphone Amplifier Microphone Head with Pre-amplification High Sensitivity

 

Description

It adopts Knowles high-sensitivity silicon microphone + pre-amplifier circuit design, with an output of about 30mw, which can directly drive ordinary 32 ohm headphones.

Board size: 18mm*15mm

Working voltage: 3v-5v DC

R5: Magnification adjustment resistor. The resistance value can be 4.7k-100k (the plug-in pad is reserved next to the chip resistor. If there is no chip resistor or the welding technology is not good, the plug-in resistor can be used.) The resistance value is higher. The higher the gain, the higher the gain.

R6: Microphone sensitivity adjustment resistance. The default is the highest sensitivity (resistance value is 0 ohms), and the resistance can be selected from 0 ohms to 10K (the plug-in pad is reserved next to the chip resistor, if there is no chip resistor or welding technology No good, plug-in resistors can be used.)

, the larger the resistance value, the lower the sensitivity.
