Note: All inputs are diode-protected and terminal grounds are connected to the
enclosure’s ground.
* 1 : Typical value.
* 2 : The value when the warm-up time has expired under the reference operating
conditon with the coupling and input impedance set at DC and 1 M Ω , respectively.
* 3 : The value when the output is received into 50 Ω at a 1 M Ω input impedance.
