TDF8599
I2C-bus controlled dual channel class-D power amplier
[1]
Required resistor accuracy for pins ADS and MOD is 1 %; see Section 9 on page 24.
[2]
Maximum leakage current from DCP pin to ground = 3
A.
[3]
DC output offset voltage is applied to the output gradually during the transition between Mute mode and Operating mode.
[4]
I2C-bus mode only.
[5]
The transition time between Mute mode and Operating mode is determined by the time constant on the SEL_MUTE pin.
[6]
The DC load valid bit DB1[D6] must be used; Section 8.6.2.1 on page 19. The DC load enable bit IB2[D2] must be reset after each load
detection cycle to prevent amplier hang-up incidents.
[7]
The output offset values can be either positive or negative. The Vth(offset) limit values (excluding Typ) are the valid absolute values.
