FUNCTIONAL DESCRIPTION
The TDA7073A/AT are dual power driver circuits in a BTL
configuration, intended for use as a power driver for servo
systems with a single supply. They are particular designed
for compact disc players and are capable of driving focus,
tracking, sled functions and spindle motors.
Because of the BTL configuration, the devices can supply
a bi-directional DC current in the load, with only a single
supply voltage. The voltage gain is fixed by internal

supply voltage range (3 to 18 V). The devices can supply
a maximum output current of 0.6 A. The outputs can be
short-circuited over the load, to the supply and to ground
at all input conditions. The differential inputs can handle
common mode input voltages from ground level up to
