Amplifier gain is – Operational From 2.5 V to 5.5 V externally configured by means of two resistors per • Thermal and Short-Circuit Protection input channel and does not require external compen- sation for settings of 1 to 10. • Surface-Mount Packaging THD+N when driving an 8- Ω load from 5 V is 0.1% at – PowerPAD™ MSOP 1 kHz, and less than 2% across the audio band of 20 – SOIC Hz to 20 kHz. For 32- Ω loads, the THD+N is reduced • Standard Operational Amplifier Pinout to less than 0.06% at 1 kHz, and is less than 1% across the audio band of 20 Hz to 20 kHz. For 10-k Ω loads, the THD+N performance is 0.01% at 1 kHz, and less than 0.02% across the audio band of 20 Hz to 20 kHz.
