PA162

Power Operational Amplifiers

DESCRIPTION

FEATURES

The ampliﬁer design is a dual power op amp on a

single monolithic die. The quad output PA162 com-

bines two dual op amp die in a single PSOP pack-

age. This approach provides a cost-effective solu-

tion to applications where multiple ampliﬁers are

required or a bridge conﬁguration is needed. Four

independent ampliﬁers coupled with low quiescent

current and very low THD makes this an ideal low-

distortion 4-channel audio ampliﬁer for applications

such as laptops and computer speakers.

♦ LOW COST

♦ WIDE BANDWIDTH - 1.1 Mhz

♦ HIGH OUTPUT CURRENT - 1.5A PER AMPLIFIER

♦ WIDE COMMON MODE RANGE Includes negative

supply

♦ WIDE SUPPLY VOLTAGE RANGE Single supply:

5V to 40V Split supplies: ± 2.5V to ± 20V

♦ LOW QUIESCIENT CURRENT

♦ VERY LOW DISTORTION

The quad output PA162DK is available in a surface

mount 20-pin PSOP, JEDEC MO-166-AB package.

Built-in thermal shutdown allows the devices to self-

protect against thermal overloads. Care must be ex-

ercised to observe the Safe Operating Area (SOA)

curve and proper heatsinking will ensure maximum

reliability.

APPLICATIONS

♦ HALF AND FULL BRIDGE MOTOR DRIVERS

♦ AUDIO POWER AMPLIFIER

Stereo - 11.3W RMS per ampliﬁer

Bridge - 22.6W RMS per two ampliﬁers

Two Bridges - 45.2W RMS per package

♦ 3 PHASE MOTOR DRIVER

3 Channels - 33.9W RMS per package

♦ IDEAL FOR SINGLE SUPPLY SYSTEMS

5V - Peripherals

The wide common mode input range includes the

negative rail, facilitating single supply applications.

This makes it possible to have a ground-based input

driving a single supply ampliﬁer with ground acting

as the second or bottom supply of the ampliﬁer.

12V - Automotive

28V - Avionic
