说明
- MIKROE-3445, MIC 2 Click Board is equipped with a small electret microphone, accompanied by a suitable pre-amplifying circuit. The small electret microphone is not capable of providing sufficient line-level output, therefore, the pre-amp has to be used. The pre-amp circuit consists of a dual op-amp and a digitally controlled potentiometer IC. Thanks to the AD5171, it is possible to control the feedback loop gain of the MCP6022 op-amp over the I2C interface, in 64 discrete steps. The AD5171 digital potentiometer IC can lock-out its wiper by means of OTP fuse bit: once locked, it will permanently retain the programmed value
