Description:The PA107 is a high-voltage, high-speed power operational amplifier that is capable of slew rates up to 3,000 V/µs, which raises the bar for single-packaged hybrids. The PA107 also improves output current performance with 1.5 A (5 A PEAK), a high gain bandwidth of 180 MHz, and can operate on single supply voltages up to 200 V. The PA107 is an attractive option for driving piezos used in medical imaging and ultrasound applications, as well as programmable power supplies for the ATE market because the high s
Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and thermal vias under the package to ensure efficient heat dissipation. A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat.
To ensure proper biasing, follow the recommended biasing circuit in the datasheet, and adjust the voltage and current limits according to the application's requirements. Additionally, consider using a biasing circuit with a low-dropout regulator to minimize noise and ensure stable operation.
For optimal performance, impedance matching is crucial. Use a pi-network or a T-network topology for impedance matching, and consider using a low-pass filter or a band-pass filter to reject harmonics and spurious signals. The output filter should be designed to match the load impedance and minimize reflections.
To protect the PA107DP, use voltage and current limiting circuits, such as a voltage regulator and a current limiter. Additionally, consider using a fuse or a polyfuse to prevent overcurrent conditions. Ensure that the input and output circuits are designed to handle the maximum voltage and current ratings of the device.
Characterize the PA107DP using a vector signal analyzer or a spectrum analyzer to measure gain, output power, and distortion. Use a load pull system to optimize the output impedance and a noise figure meter to measure the noise figure. Follow the recommended test procedures outlined in the datasheet and application notes.
