The L-17D Log Video Amplifier IC is flexible, powerful, and easy to tune.

How can the L-17D help you? >


Anadyne Inc. has designed precision analog devices since 1986.

Our main product is the L-17D logarithmic amplifier.

The L-17D DC to 80 Mhz IC includes:

  • 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.

History of the L-17D

ANADYNE, INC. was incorporated in Santa Cruz, California, in May, 1986, for the purpose of the design and sale of high-precision analog integrated circuits. ANADYNE is best known for its development of logarithmic video-bandwidth amplifiers (LVAs). The L-17C LVA was introduced to the world market in 1988. This award-winning product became recognized as the world leader in the areas of stability, dynamic range, and low noise, among LVAs in the DC- to 50-MHz bandwidth range. The L-17C has been used in many applications on a global basis for two decades.

In 2006, the L-17C was replaced by a higher-performance LVA, designated the L-17D. Since then additional improvements to the original L-17D have been made, resulting in the currently available version 3 of the L-17D. Version 3 is offered in two different pin-outs designated pinout A or pinout B. Because of the current interest in hybrid circuit configurations, the new circuit it available in die form as well, which is designated: L-2010.
