Notes
1. The supply voltage range at pin V_P1 is from 1.9 to 18 V. Pin V_P2 is used for the voltage range from 6 to 30 V.
2. Measured with low-pass filter 30 kHz.
3. Noise output voltage measured with a bandwidth of 20 Hz to 20 kHz, unweighted. R_s = 5 kΩ.
4. RMS output voltage in mute is measured with V_i = 200 mV (RMS); f = 1 kHz.
5. DC output offset voltage is measured between the signal output and the 0.5V_P output.
6. The ripple rejection is measured with a ripple voltage of 200 mV (RMS) applied to the positive supply rail (R_s = 0 kΩ).
7. DC output offset voltage is measured between the two signal outputs.
