Differential, high CMRR, analog input
Programmable input attenuation/gain to support up to four drive levels
Noiseless Gain compression of up to 16 dB with programmable attack and decay.
Compressor controlled by monitoring estimated THD
Soft mute / un-mute for pop control
Adaptive pulse injection prevents missing pulses due to over modulation which
maximizes useful output swing.
Programmable current limiting based on FET VDS
Optimized for low distortion at low switching frequency (approximation 110KHz)
Dual Clocked PWM modulators for 3 state switching
External gain control / internal integrator components
Controls 4 external FETS with switching optimized for low EMI
Oscillation frequency selectable by I
Anti-pop shunt driver
18bit, mono
I
Hybrid architecture, area optimized for Bass
Full bandwidth supported by off loading the interpolator function
Synchronization with modulator
On board STEP-UP step up converter, synchronized to the modulator frequency
Drives external NFET switch
Externally compensated
Soft start and current limiting
Critical modes controllable by mode pins for bus-less operation
I
Offset, short, open, overcurrent, over temperature
I
Faults pin used to report errors in bus-less environment
Clipping reported at a separate pin
Abnormal supply current detection disables input power for fail safe operation
Output current limiting
Power control
Latching control of an external PMOS power switch for safety related faults.
Power is switched off for safety related faults of abnormal supply current,
excessive internal or external temperature, or persistent output stage over-current
that fails to be controlled by the pulse-by-pulse current limiting method
