L-17D Log Video Amplifier IC

  • ANADYNE's Fast Ultra Low Noise Preamp; Compatible with many different input topologies for maximum flexibility.

  • Two More Linear Amplifiers; Integrated amplifiers allow for very low propagation delay and high dynamic range.

  • Eleven Log and Linear Extension Stages; Many of the stages are tunable making very precise and custom non linear transfers possible.

  • Direct Summing Junction for Dual LVA Circuits; Two or more L-17D's can be used in combination for even more dynamic range.

  • Output Amplifier Stage; Our output amplifier can drive 50 ohm cables and now comes with a short circuit protection option.

  • Hermetically sealed and thoroughly screened for high reliability applications.
