STMicroelectronics X-NUCLEO-CCA01M1 Sound Terminal Expansion Board PWM

The X-NUCLEO-CCA01M1 expansion board is based on the STA350BW Sound Terminal® 2.1-channel digital audio amplifier chip. The STA350BW device integrates digital audio processing, digital amplifier control and an FFX™ digital power output stage providing high-quality, high-efficiency and all-digital amplification.

• Output: 2-channel (Stereo) ternary PWM (2 x 50W into 6Ω);• Audio input: serial I²S bus for standard audio streaming;• Control input: serial I²C bus with selectable device address;• FFX™ technology providing 100dB SNR and 100dB dynamic range;• On-board output filter circuits with ESD protection;• Compatible with STM32 Nucleo-64 boards;• ST morpho connector (upward and downward);• Arduino v3 Shield connector (upward) for multiple board connections;• Screw terminals for loudspeaker connections;• Separate connector for output stage power supply (+5 to +25Vdc)

Two X-NUCLEO-CCA01M1 expansion boards can be plugged onto the same STM32 Nucleo host to build a four-channel system.
