TIDA-00023 Reference Design

Texas Instruments

Reference Design for Implementation of the Load Sharing Concept for Large-Signal Applications


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 voltageUp to 24VPP output swingThird-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
