对数和对数比放大器 LOGARITHMIC AND LOG RATIO AMPLIFIERS
The 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 reference 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 temperature range of 5°C to +75°C.
