LOG112
LOG2112SBOS246D – JUNE 2002 – REVISED APRIL 2005
DESCRIPTIONThe LOG112 and LOG2112 are versatile integrated circuits
that compute the logarithm or log ratio of an input current
relative to a reference current. VLOGOUT of the LOG112 and
LOG2112 are trimmed to 0.5V per decade of input current,
ensuring high precision over a wide dynamic range of input
signals.
The LOG112 and LOG2112 features a 2.5V voltage refer-
ence that may be used to generate a precision current
reference using an external resistor.
Low DC offset voltage and temperature drift allow accurate
measurement of low-level signals over the specified tem-
perature range of –5°C to +75°C.
