Notes
1. The channel separation is dependent on the capacitor C2 connected to the IN- input. The channel separation for low
2. The frequency response is externally fixed by the input and output coupling capacitors.
3. The noise output voltage is measured in a bandwidth of 20 Hz up to 20 kHz, unweighted.
4. The common mode rejection ratio is measured at the output with a voltage source V
5. Supply voltage ripple rejection is measured at the output using a ripple amplitude of 2 V (p-p).
