ROV07-271K on stock ei and e2: Noise voltage Fig. 4 The principle of noise rejection With the BA3121, the elimination level of the noise is ex- pressed as: CMMR = 2010g (eo/ei) (ei = ei = e2) Therefore, CMRR 41dB can be guaranteed. OOperation notes (1) Maintain a ratio of 2: 1 for the values of the capaci- tors connected to pin 2 (Vml) and pin 6 (Vm2) to keep the ripple rejection ratio stable. If this ratio is maintained, the ripple rejection ratio will not vary significantly even if the capacitance values are halved. (2) If the value of the capacitor connected to pin 2 (Vml) in the example is doubled, the bass-region CMMR will be +6dB, and if it is halved, it will be - 6dB (see Fig. 16).
