Apex Microtechnology has expanded its portfolio of high-voltage operational amplifiers with the PA99, an off-the-shelf, single-package 2500-V power amp that addresses the demand for high-voltage ...
A lot of the analog-circuit conversation these days is centered on low-power and thus low-voltage considerations. That makes sense for operational amplifiers (op amps), of course, since these basic ...
Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...
Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...
You'll need a pretty amazing pair of speaker to justify this amp, but it's made for the truly hardcore, with equally hardcore speakers ...
It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...
