Notes to the characteristics
1. The circuit is DC adjusted at VP = 6 to 18 V and AC operating at VP = 8.5 to 18 V
2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2
3. Conditions: V14 = 0 V; short circuit to ground; switch V14 to MUTE or ON condition, rise time at V14 = ≥ 10 µs
4. Frequency response externally fixed
5. Ripple rejection measured at the output with a source-impedance of 0 Ω (maximum ripple amplitude of 2 V) and a
frequency between 100 Hz and 10 kHz
6. Mismatching is given by the following equation:
∆ Zi = Z----i--1-Z---–-i--1-Z----i-2- × 100°⁄°
∆ Zi = Z----i--3-Z---–-i--3-Z----i-4- × 100°⁄°
7. Noise measured in a bandwidth of 20 Hz to 20 kHz
8. Noise output voltage independent of RS (VI = 0 V)
9. Common mode rejection ratio measured at the output with both inputs tied together. VI(RMS) < 3.5 V;
f = 100 Hz - 10 kHz
