2) "A" and "GND" : single-ended input mode (Non-inverting amplifier)
3) "GND" and "－B " : single-ended input mode (Inverting amplifier)
⑤OUTPUT (THRU / LPF)
Selection switch for output stage LPF.
The output of the amplifier is output as it is with "THRU".
It is output through LPF of cutoff frequency 1 MHz with "LPF".
The output resistance is 50 Ω.
⑥POWER LED
