The gain of each amplifier is fixed at 40 dB. A special feature of this device is the mute/stand-by switch which has the following features: · low stand-by current (< 100 mA) · low mute/stand-by switching current (low cost supply switch) · mute condition.

All characteristics are measured using the circuit shown in Fig.4. 2. The circuit is DC adjusted at VP = 6 V to 18 V and AC operating at VP = 8,5 V to 18 V. 3. At 18 V < VP < 30 V the DC output voltage . VP/2. 4. Output power is measured directly at the output pins of the IC. 5. Frequency response externally fixed. 6. Ripple rejection measured at the output with a source impedance of 0 W (maximum ripple amplitude of 2 V) and a frequency between 100 Hz and 10 kHz. 7. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz. 8. Noise output voltage independent of RS (VI = 0 V).
