Description The MAX98355A/MAX98355B are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D efficiency. These ICs offer five selectable gain settings (3dB, 6dB, 9dB, 12dB, and 15dB) set by a single gain-select input (GAIN). The digital audio interface is highly flexible with the MAX98355A supporting I²S […]

the Design Idea circuit shown below is a simple implementation of an iterated unimodal map, reminiscent of the logistic or Verhulst map encountered in the study of nonlinear dynamics. It is useful to show chaotic discrete-time dynamics to students, or as a random number generator. Specifically, the circuit implements: Vk+1 = rF(Vk), where F is

Capacitors Capacitors are two-terminal components used for filtering, energy storage, voltage spike suppression, and many other applications. In their simplest form, they consist of two parallel plates separated by an insulating material called a dielectric. Capacitors store electrical charge. The unit of capacitance is Farad (F), attributed to Michael Faraday who was a pioneer
