NJM2204A - JRC

NJM2204A LOG AMPLIFIER

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.
