Logamp using Texas Instruments SN56502 or SN76502 in combination with three SN52741 opamps can handle input voltage range greater than 80 dB with respect to 1 V P-P. Inputs are limited by reducing supply voltages of input amplifiers to 14 V.Gains of input amplifiers are adjusted to achieve smooth transitions.- The Linear and Interface Circuits Data Bookfor Design Engineers, Texas Instruments, Dallas, TX, 1973, p 7-45.
