Notes
1. Frequency response externally fixed.
2. Vripple = Vripple(max) = 2 V (p-p), Rs = 0 Ω.
3. Dynamic Distortion Detector (DDD) active, pin 4 is low.
4. Common mode rejection ratio measured at the output (over RL) with both inputs tied together,
common ≤ 3.5 V (RMS), f = 100 Hz to 10 kHz, Rs = 0 Ω.

5. Common mode rejection ratio measured at the output (over RL) with both inputs tied together, Vcommon ≤3.5 V (RMS),
f = 1 kHz, Rs = 45 kΩ. The mismatch of the input coupling capacitors is excluded.
