3) A DC servo using a dual op amp can also be used to automatically null any offset voltage.

This DC servo will only eliminate the turn off pop since the RC time constant of the DC servo

is very slow. Please contact Tripath sales for additional information on the DC servo circuit.

Protection Circuits

The TA2024C is guarded against over-temperature and over-current conditions. When the

device goes into an over-temperature or over-current state, the FAULT pin goes to a logic HIGH

state indicating a fault condition. When this occurs, the amplifier is muted, all outputs are TRI-

STATED, and will float to 1/2 of VDD.

Over-temperature Protection

An over-temperature fault occurs if the junction temperature of the part exceeds approximately

155°C. The thermal hysteresis of the part is approximately 45°C, therefore the fault will

automatically clear when the junction temperature drops below 110°C.
