Power Operational Amplifiers
FEATURES

DESCRIPTION

♦ 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 QUIESCENT CURRENT
♦ VERY LOW DISTORTION

The amplifier design is a dual power op amp on a
single monolithic die. The quad output PA162 combines two dual op amp die in a single PSOP package. This approach provides a cost-effective solution 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 lowdistortion 4-channel audio amplifier for applications
such as laptops and computer speakers.

APPLICATIONS

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 selfprotect against thermal overloads. Care must be exercised to observe the Safe Operating Area (SOA)
curve and proper heatsinking will ensure maximum
reliability.

♦ PACKAGING OPTIONS
t 20-Pin PSOP, JEDEC MO-166-AB (PA162DK)

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.
