PA75CD - Apex Microtechnology

Description: The PA75 is a single chip, dual power operational amplifier capable of 2.5A of continuous output current on 5V to 40V single supplies. The IC design of the PA75 utilizes a dual power amplifier on a single monolithic die. Side B of the chip is configured as a unity gain buffer to increase the current capability of the side A “master”. Two PA75 amplifiers can be used to provide a cost effective solution for applications where multiple amplifiers are required or a bridge configuration is needed. Very low harmo

PA75CD Frequently Asked Questions (FAQs)

  • A good PCB layout for the PA75CD should minimize parasitic inductance and capacitance. Use a solid ground plane, keep signal traces short and wide, and avoid vias under the device. Apex Microtechnology provides a recommended PCB layout in their application notes.
  • To ensure stability, follow the recommended compensation network and component values. Additionally, ensure that the output stage is properly bypassed, and the input stage is properly terminated. Apex Microtechnology provides a stability analysis in their application notes.
  • The maximum safe operating area (SOA) for the PA75CD is defined by the maximum voltage and current ratings. The device can operate safely up to 100V and 10A, but derating is required for high-temperature operation. Consult the datasheet for detailed SOA information.
  • Use voltage and current limiting circuits to protect the PA75CD from overvoltage and overcurrent conditions. Apex Microtechnology recommends using a voltage clamp and a current sense resistor to prevent damage.
  • The thermal derating curve for the PA75CD is provided in the datasheet. The device can operate up to 150°C, but derating is required above 125°C. Consult the datasheet for detailed thermal derating information.
