Typical values are at T
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
Note 6: Output swing is specified with respect to V
Note 7: For typical applications, an external 5V supply is not required. Therefore, set REGEN = 5V. If thermal performance is a
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.
