Microphone input using
The operational amplifier connects the embedded microphone to the audio preamplifier to set the gain by using and jumpers; Both must be set or deleted at the same time You can select each of the following gain values by modifying the jumper position: (default setting and both are off) (and both are on) Note: The series ohmic resistor is reserved for future impedance adaptation facilities. Under specific amplifier setting conditions, this allows easy insertion of capacitors or any other bipolar devices on the audio path. On the other hand, it is a default ohmic resistor that allows disconnection from the audio input path for custom use. The audio preamplifier is supported by a dedicated low dropout regulator, microphone input, headphone output, evaluation kit, and connected to the microcontroller Two channel audio amplifier driven mono/stereo audio playback is a single bridge connected load amplifier designed to drive speakers with low to ohmic impedance This amplifier can be dynamically reconfigured to drive two stereo single ended signals into headphones
headphone output
And should be set or removed together Telephone jack Stereo evaluation kit Hardware development board User's Guide – – MM/DD/YYYY Use the ready-made/inch () stereo headphone jack When the plug is not inserted, the control switch is closed/the voltage divider pulls/the input is pulled down When the plug is inserted into the jack, the resistor is disconnected/the input is pulled up Mono speaker (connector) It is also physically disconnected from the/output so that the speaker will not emit sound when the headset is plugged in. The device port complies with the Universal Serial Bus version of the full speed device specification. The device's miniature socket ohmic resistor and the (embedded) ohmic output impedance together with the full speed channel driver establish the ohmic differential impedance and detect through the implementation plug-in from the establishment of the frequency divider bridge (the level is reduced to a compatible level) Figure Analog interface analog reference voltage reference is based on (precision micro power shunt voltage reference
