A strip of SL523s can be directly coupled and decoupling is provided on each amplifier RF limiting occurs at an input voltage of 25mV RMS but the device will withstand input voltages up to 1 8V RMS without damage The device is also available as the 5962-89803 which has guaranteed operation over the full Military Temperature Range and is screened to MIL-STD-883 Class B.
