DESCRIPTION

The ampliﬁer design is a dual power op amp on a single

monolithic die. This approach provides a cost-effective solu-

tion to applications where multiple ampliﬁers are required or

a bridge conﬁguration is needed. Very low harmonic distortion

of 0.02% THD and low I_Qmakes the PA60 a good solution for

low power audio applications such as laptops and computer

speakers.

TYPICAL APPLICATION

R1 and R2 set up Ampliﬁer A as non-inverting. Ampliﬁer

B is set up as a unity gain inverter driven from the output of

Ampliﬁer A. Note that Ampliﬁer B inverts the signals about

the reference node, which is set at mid-supply by R5 and

R6. When the command input is midrange, so is the output

of Ampliﬁer A. Since this is also equivalent to the reference

node voltage, the output of Ampliﬁer B is the same resulting

in 0V across the motor. Inputs more positive than 5V result in

motor current ﬂow from left to right (see Figure 2). Inputs less

than 5V drive the motor in the opposite direction.

Theampliﬁersareespeciallywell-suitedforapplicationssuch

as this. The extended common mode range allows command

inputs as low as 0V. The output swing lets it drive within 2V

of the supply at an output of 1A. This means that a command

input that ranges from 0 to 10V will drive a 24V motor from

full scale CCW to full scale CW at ±1A.
