TI's Audio over Light Demo showcases TI's audio operational amplifieres (op amps) and power op amps, as well as alternative methods of transmitting analog signals. We build the demo using TI Designs - Precision reference designs. You can recreate it using the following reference designs:

• Analog PWM generator reference design with 5-V, 500kHz PWM output (TIPD108)
• 1-MHz, single-supply, photodiode amplifier reference design (TIPD176)
• Single-supply op amp reference design with drive-to-true GND (TIPD145)
• Active volume control reference design for professional audio (TIPD136)
• Analog, active crossover reference design for two-way loudspeakers (TIPD134)

The WEBENCH® Filter Designer Demo walks the viewer through the tool in an easy-to-follow and interactive demonstration. It highlights how the tool lets you design, optimize, and simulate complete multi-stage active filter solutions within minutes.
