The input impedance, RIN, is dependent on device gain. Larger input capacitors decrease the corner frequency. See the following table for input
impedance values.
G0 Voltage G1 Voltage RIN
≤0.6V ≤0.6V 26.4kΩ
≥1.4V ≤0.6V 19.8kΩ
≤0.6V ≥1.4V 16.5kΩ
≥1.4V ≥1.4V 13.2kΩ
For a given high-pass cutoff frequency, the minimum input coupling capacitor is found as:
Absolute Maximum Ratings (@TA = +25°C, unless otherwise specified.) (Note 4)
These are stress ratings only and functional operation is not implied. Exposure to absolute maximum ratings for prolonged time periods may
affect device reliability. All voltages are with respect to ground.

Note: 4. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be

Power Supply Decoupling Capacitors
The PAM8901 / PAM8908 TrueCapFree headphone amplifier requires adequate power supply decoupling to ensure that output noise and total
harmonic distortion (THD) remain low. Use good low equivalent-series-resistance (ESR) ceramic capacitors (X5R material or better is required for
best performance). Place a 2.2µF capacitor within 5mm of the PVDD pin. Reducing the distance between the decoupling capacitor and PVDD
minimizes parasitic inductance and resistance, improving PAM8901 / PAM8908 supply rejection performance. Use 0402 or smaller size capacitors
if possible.
