Apex Microtechnology MSA240 Pulse Width Modulation Amplifiers are a cost-effective solution for industrial applications with outstanding performance. The MSA240 amplifiers include an oscillator, comparator, error amplifier, current limit comparators, 5V reference, a smart controller, and a full-bridge output circuit. The switching frequency is programmable up to 50kHz. The Apex Microtechnology MSA240 is built on a thermally conductive but electrically insulating substrate that can be mounted to a heatsink.
