The PAM8610, manufactured by Power Analog Microelectronics, is a high-performance, 10W (per channel) stereo class-D audio amplifier featuring DC volume control. This component is designed to deliver low THD+N (0.1%), low EMI, and high efficiency (>90%), making it ideal for high-quality sound reproduction in a variety of applications such as flat monitor/LCD TVs, multi-media speaker systems, DVD players, game machines, boomboxes, and musical instruments. Operating off a 7V to 15V supply, the PAM8610 distinguishes itself with its 32-step DC volume control ranging from -75dB to 32dB, shutdown/mute/fade functions, and comprehensive protection against overcurrent, thermal, and short-circuit conditions. Its low quiescent current, pop noise suppression, and minimal external component requirement further enhance its appeal for compact and efficient audio solutions. The PAM8610 is available in a compact 40-pin QFN 6mm*6mm package, ensuring a small footprint for space-constrained applications. Compliance with RoHS standards underscores its environmental consideration. With its advanced features and high integration level, the PAM8610 offers a compelling option for designers seeking to incorporate robust audio amplification with fine-grained volume control in their electronic projects.

sEMG-DAQ is a wearable 6 channel data acquisition unit for capturing surface electromyographic (sEMG) signals from human arm muscles using SJ2-3593D jack connectors while conditioning, digitizing, processing and transmitting them as sEMG data to an external AI accelerated board through an SM12B-SRSS IDC connector where AI models are run for various applications including robotic control, muscle signals medical assessment and gesture recognition. The board leverages an INA125P instrumentation amplifier together with filter stages utilizing LM324QT op-amps for conditioning and an STM32G4A1VET6 microcontroller for the digitization, processing and data transmission of the signals. Since AI models can only be as good as the data, the design of such a DAQ is necessary to ensure clean, reliable and real-time data for AI applications requiring sEMG data. The board also has USB-FS and JTAG to cater for debugging. The power (5V) is fed through a screw terminal and is regulated by two LDK320AM LDO regulators to offer 5V, 3.3V and 1.8V to meet the requirements of various components on the board.
