TYPICAL APPLICATION
R1 and R2 set up Amplifier A as non-inverting. Ampli-
fier 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 out-
put 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 3). Inputs less
than 5V drive the motor in the opposite direction.
