So, IF = RF when LO > 0, and IF = -RF when LO 0. This op-amp mixer offers several advantages. It is dc coupled on all three ports, which could be an advantage for some applications. A diodebridge ...

There are plenty of audio mixers on the market, and the vast majority all look the same. If you wanted something different, ...

The resulting waves are added together in a mixer, consisting of a dual-gang ... two coax cables connected to an oscilloscope. All op amps are low-power MCP6004 types that consume just 100 uA ...

This audio mixer circuit uses an LM3900 IC but is not a profesional audio dj mixer. The IC houses four integrated Norton amplifiers. The advantage of using the four op amps is that they only need a ...

You might be able to get away with a simple resistive mixer, but with 7 or 8 sources thats pushing it pretty far. You'd most likely be better served by a small op-amp mixer. Ciruit plans are easy ...

Some op amps, such as the AD8041 from Analog Devices and the EL5100 from Intersil, provide a disable pin, which allows you to parallel the outputs of several op amps for video multiplexing.In addition ...

If the op-amp gain is large ... A four-input audio mixer can be configured in three ways: as an inverting-amplifier mixer circuit (left); as a balanced mixer with two positive and two negative ...
