LOG AMPLIFIER
NJM2204A
■ GENERAL DESCRIPTION
The NJM2204A is an integrated IF limitting amplifier which
contains temperature compensated reference power supply, 6 stage
differential limitting amplifier and 6 stage logarithmic suppression
circuit.
Its votage gain is 58dB and linearity is ±1dB within 50dB log
dynamic range. The voltage gain and log dynamic range are
enlarged by connecting multiple stages.
The NJM2204A is suitable to telecommunication equipment.
