HiFi Rose’s RA280 Integrated Amplifier Features GaN FET Technology and A Much Lower Price Than The Flagship RA180. ... The RA280”s power supply circuit was independently developed by HiFi Rose. This ...

In a typical automotive video application, the video digital-to-analog converter (DAC)—from a rear camera or DVD player, for example—is followed by a low-pass reconstruction filter ...

When a MOSFET or IGBT gate-threshold voltage is higher than the available drive voltage, it's standard to use an op amp or other driver to bridge the difference. This circuit ...

The Hotwire replaces those heavy components with a MOSFET power section that emulates the sound without the bulk, in fact the whole amp weighs less than 25lbs. The VT12 has a reconfigurable analog ...
