LOG114
SBOS301A -MAY 2004 -REVISED MARCH 2007 Single-Supply, High-Speed, Precision
LOGARITHMIC AMPLIFIER
FEATURES DESCRIPTION D ADVANTAGES: The LOG114 is specifically designed for measuring
low-level and wide dynamic range currents in
communications, lasers, medical, and industrial
systems. The device computes the logarithm or log-ratio
of an input current or voltage relative to a reference
current or voltage (logarithmic transimpedance
amplifier). D
