What are the key features of OPA2691I-14DG4?

  • Current-feedback architecture delivers 1500 V/µs slew rate and 225 MHz bandwidth, enabling distortion-free amplification of high-frequency video and wideband RF signals
  • Dual-channel configuration in a 14-pin SOIC package allows differential signal amplification or simultaneous dual-channel gain stages without requiring two separate op-amp ICs
  • 50 dB minimum common-mode rejection ratio with only 4.3 mV maximum input offset voltage enables precision high-speed signal conditioning in noise-sensitive measurement applications

What is OPA2691I-14DG4 used for?

The OPA2691I-14DG4 is designed for high-speed analog signal chains including video distribution amplifiers, cable driver stages, and ADC input buffer circuits requiring bandwidths beyond 100 MHz. Its current-feedback topology with 1500 V/µs slew rate makes it ideal for driving low-impedance coaxial cables and back-terminated video lines at standard 75 Ω impedances. The dual-channel architecture also suits differential I/Q signal processing in software-defined radio (SDR) and communications baseband circuits.
