... The processor portion of the TA0102A is operated from a 5-volt supply (between V5 and AGND). In the generation of the complementary modulation pattern for the output MOSFETs, the processor inserts a “break-before-make” dead time between when it turns one transistor off and it turns the other one on in order to minimize shoot-through currents in the MOSFETs. The dead time can be programmed by setting the break-before-make control bits, BBM0 and BBM1 ...

... IN1 and IN2 in the Test/Application Circuit. Nulling should be performed with the inputs shorted to ground. It should be noted that even after nulling, the DC voltage on the output of a TA0102A amplifier with no load in mute mode is approximately 2.5V. This offset does not need to be nulled. The output impedance of the amplifier in mute mode is approximately 10 KOhms ...

... Bridged Operation Note that the two channels of a TA0102A amplifier can be used to provide a single, bridged amplifier of almost four times the output power of one of the single-ended amplifier channels. To configure a bridged amplifier, the input to one TA0102A channel must be the inverted signal of the input to the other channel ...
