*1. Each setting is measured without connecting feedback capacitor C₂ for variable gain amplifier, high-frequency bandwidth is not limited.
Output gain setting of each characteristics are shown below;
[A]: 50.0 dB setting (R₁ = 33kΩ, R₂ = 330kΩ)
[B]: 36.8 dB setting (R₁ = 150kΩ, R₂ = 330kΩ)
[C]: 30.0 dB setting (R₁ = 330kΩ, R₂ = 330kΩ)
