HOW DOES IT WORK?
AudioAMP 12 Click is based on the TS2007FC, a filter-free class-D audio amplifier from STMicroelectronics. The amplifier can work in differential configuration or single-ended input configuration. You can choose one over the INPUT SEL jumper, where the SE (single-ended) is set by default. The amplifier is a monolithic, fully differential input/output amplifier, which includes a common mode feedback loop that controls the output bias value to average it in correlation to the DC common mode input voltage range. This, in turn, allows the amplifier always to have a maximum output voltage swing and maximize the output power. Compared to the single-ended topology, the output is four times higher for the same power supply voltages.
The amplifier allows switching between two fixed gains: 6 or 12dB (2 or 4V/V gain). It also features thermal shutdown protection, output short-circuit protection, and a low pop-and-click noise, where the signal-to-noise ratio is typically 90dB. The pop-and-click reduction circuitry and low ON/OFF switching noise allow the amplifier to start within the 1ms typically. You can also choose the Standby mode function, which keeps the current consumption down to 1μA.
This Click board™ features a standard 3.5mm audio jack to connect the audio input. In addition to the audio jack, there is also an unpopulated 3-pin header if you want to connect the audio input by other means. AudioAMP 12 Click allows connecting one speaker over the onboard terminal. This Click board™ uses general-purpose input/output pins to communicate with the host MCU. You can select one of the available gains with IOs logic states using the GS pin. The STB pin is a Standby pin with active LOW logic.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
