Low-cost integrated resistor networks can be used to implement a low-parts-count two-op-amp differential amplifier with low common-mode gain. Integrated onto a common substrate and processed together, ...
Back on December 3, 2024, a Design Idea (DI) was published, “Single-supply single-ended inputs to pseudo class A/B differential output amp,” which created some discussion about using the circuit as a ...
Eliminating the need for external amplifiers on each sensor input channel, the MAXQ7670A system-on-chip (SoC), mixed-signal microcontroller (MCU) integrates a differential amplifier and all necessary ...
If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...
LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. The K2-W's first-stage differencing ...
A differential probe, a device for measuring the voltage between two points in a circuit rather than the voltage between a point and ground, it an extremely useful addition to any electronics bench.
