DESCRIPTION
The TDB7910 and TDA7910 are internally compensated medium power operational amplifiers intended for use in those applications requiring load
currents of several hundred milliamperes. Applications include servo amplifiers, driver interfaces,
precision power comparators and motor speed
control. These amplifiers are designed to operate
from a single or dual power supplies and the input
common-mode range includes the negative supply
if balance inputs are tied to the negative supply.
The TDB7910 and TDA7910 are thermal overload
and short-circuit protected.
