TYPICAL APPLICATION

DESCRIPTION

R1 and R2 set up ampliﬁer A in a non-inverting gain of 2.8.

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

of amp A. Note that amp B inverts signals about the reference

node, which is set at mid-supply (14V) by R5 and R6. When

the command input is 5V, the output of amp A is 14V. Since

this is equal to the reference node voltage, the output of amp

B is also 14V, resulting in 0V across the motor. Inputs more

positive than 5V result in motor current ﬂow from left to right

(see Figure 1). Inputs less positive than 5V drive the motor in

the opposite direction.

The ampliﬁers are especially well-suited for this application.

Theextendedcommonmoderangeallowscommandinputsas

low as 0V. Its superior output swing abilities let it drive within

2V of supply at an output current of 2A. This means that a

command input that ranges from 0.714V to 9.286V will drive a

24V motor from full scale CCW to full scale CW at up to ±2A. A

single power op amp with an output swing capability of Vs –6

would require ±30V supplies and would be required to swing

48V p-p at twice the speed to deliver an equivalent drive.

Theampliﬁerdesignconsistsofdualmonolithicinputandoutput

stages to achieve the desired input and output characteristics

of the PA74 and PA76. The input stage utilizes a dual power op

amp on a single chip monolithic that drives the output stages.

The output stages are conﬁgured in a non inverting unity gain

buffer conﬁguration. The output stages of the ampliﬁer are also

compensatedforstability.ThePA74andPA76dualampliﬁersare

designedwithbothmonolithicandhybridtechnologiesproviding

acosteffectivesolutionforapplicationsrequiringmultipleampli-

ﬁers per board or bridge mode conﬁgurations. Both ampliﬁers

are internally compensated but are not recommended for use

as unity gain followers.

Thisdualhybridcircuitutilizesaberyllia(BeO)substrate,thick

ﬁlm resistors, ceramic capacitors and monolithic ampliﬁers to

maximizereliabilityandpowerhandlingcapability,minimizesize

andgivetopperformance.Ultrasonicallybondedaluminumwires

provide reliable interconnections at all operating temperatures.

The 8-Pin TO-3 package is hermetically sealed and electrically

isolated. The use of compressible isolation washers voids the

warranty.
