Note 4: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 5: Stereo mode (MONO = GND) specified with 8Ω resistive load in series with a 68μH inductive load connected across BTL
outputs. Mono mode (MONO = 5V) specified with a 4Ω resistive load in series with a 33μH inductive load connected
across BTL outputs.
Note 6: Output swing is specified with respect to V
COM.
Note 7: For typical applications, an external 5V supply is not required. Therefore, set REGEN = 5V. If thermal performance is a
concern, set REGEN = 0V and provide an external regulated 5V supply.
Note 8: Output amplifier gain is defined as:
Note 9: Amplifier inputs AC-coupled to GND.
Note 10: Specified at room temperature with an 8Ω resistive load in series with a 68μH inductive load connected across BTL outputs.
Mode transitions controlled by SHDN control pin.
