DC-Coupled Audio Amplifier

Schematic Diagrams      Comments Off on DC-Coupled Audio Amplifier

Designs for audio amplifiers with DC coupling to the load are not often encountered these days, even though they offer definite advantages. One advantage is that there is no need for the complication of a second (symmetric) power supply; another is good frequency and phase response. Also, no special electrolytic… Read more »

Lowest DC Leakage Capacitors

Schematic Diagrams      Comments Off on Lowest DC Leakage Capacitors

Lowest DC Leakage Capacitors Vishay Intertechnology, Inc. introduced the new TL3 series of TANTAMOUNT® surface-mount tantalum molded chip capacitors, the industry’s first such devices to offer DC leakage current (DCL) as low as 0.005 CV, a capability that enables system designers to extend battery run-time in portable devices. Offered with… Read more »
