2N5089 is an NPN amplifier bipolar junction transistor. It operates as a switch in saturation mode and as an amplifier in the active region. The silicon-based transistor is designed mainly for audio signal amplification to amplify the weak base signal and produce a strong output signal at the collector terminal in low power systems. This … Read more
2N5457 is a general-purpose N-channel Junction Field Effect Transistor with Drain and Source interchangeable feature. It operates in depletion-mode and requires reverse biasing to turn off. Because depletion types MOSFETs act like a normally closed switch. It has high (AC and DC) input impedance, contrary to other MOSFETs. It is a CMOS technology device used … Read more
PT8211 is a 16-Bit dual-channel Digital to Analogue converter chip. It is typically a dual-channel DAC that is specifically intended for the applications concerned with digital audio. This DAC chip uses CMOS technology. As the name suggests, it depends on 16-bit and the inner engineering depends on the R-2R resistor ladder network. R-2R ladder is … Read more
SDS011 is an air quality measurement sensor which can be used to get dust particles and smoke concentration in the air. More precisely, it can measure particulate matter (MP) concentrations in the air. It can detect the dust particles concentration between 0.3 to 10um. Most importantly, Nova PM dust sensor provides an interrupt based response … Read more
