Using the THS3091 high voltage, low distortion current-feedback op amp, this reference design showcases the technique and the benefits of configuring multiple op-amps in a load sharing configuration when driving high voltage signals into heavy loads. Supported by a full scale application report, the design can be easily adjusted for a given application.
- 15V supply voltage
- Up to 24VPP output swing
- Third-Harmonic Distortion of 32dBc when driving a 20VPP, 70MHz sine wave into a 100Ω load (double-terminated 50Ω cable)
- Second-Harmonic Distortion of 38dBc when driving a 20VPP, 70MHz sine wave into a 100Ω load (double-terminated 50Ω cable)
- High Current Drive Capability (up to 400mA with two THS3091 op amps)
- This reference design has been lab tested and is supported with design files and a design guide
