Hybrid power op amp delivers 2,000 Wrms output power
The PA30 power op amp is capable of 2,000 Wrms output power–up to 8,000
W pulse–from dc to 40 kHz. The device's continuous output current is
rated at 50 A, and its peak output current can exceed 100 A. Power MOSFETs
are used for the output stages to ensure no second breakdown, and on-chip
temperature sensors provide thermal protection. The amp has a typical
slew rate of 45 V/μs and operates from 30 to 200-V rail-to-rail voltage
ranges. The device's external current limiting can be configured for
Kelvin sensing, as well as for multislope foldover limiting. The PA30 is
packaged in a 2.80-in. (W) x 2.20-in. (L) x 0.422-in. (H) sidelead package
that provides a solid, flat heat-sinking surface. ($1,585
ea/100–evaluation units available stock.) Apex Microtechnology Corp.
