Notes
1. Frequency response externally fixed.
2. V_ripple = V_ripple(max) = 2 V (p-p), R_s = 0 Ω.
3. Dynamic Distortion Detector (DDD) active, pin 4 is low.
4. Common mode rejection ratio measured at the output (over R_L) with both inputs tied together,
V_common ≤ 3.5 V (RMS), f = 100 Hz to 10 kHz, R_s = 0 Ω.
5. Common mode rejection ratio measured at the output (over R_L) with both inputs tied together, V_common ≤3.5 V (RMS),
f = 1 kHz, R_s = 45 kΩ. The mismatch of the input coupling capacitors is excluded.
