PA162PA162 PA162 Power Operational Amplifiers DESCRIPTION FEATURES The amplifier design is a dual power op amp on a LOW COST single monolithic die. The quad output PA162 com- WIDE BANDWIDTH - 1.1 Mhz bines two dual op amp die in a single PSOP pack- HIGH OUTPUT CURRENT - 1.5A PER AMPLIFIER age. This approach provides a cost-effective solu- WIDE COMMON MODE RANGE Includes negative tion to applications where multiple amplifiers are supply required or a bridge configuration is needed. Four WIDE SUPPLY VOLTAGE RANGE Single supply: independent amplifiers coupled with low quiescent 5V to 40V Split supplies: 2.5V to 20V current and very low THD makes this an ideal low- LOW QUIESCENT CURRENT distortion 4-channel audio amplifier for applications VERY LOW DISTORTION such as laptops and computer speakers. The quad output PA162DK is available in a surface APPLICATIONS mount 20-pin PSOP, JEDEC MO-166-AB package. HALF AND FULL BRIDGE MOTOR DRIVERS Built-in thermal shutdown allows the devices to self- AUDIO POWER AMPLIFIER protect against thermal overloads.

Two Bridges - 45.2W RMS per package 3 PHASE MOTOR DRIVER The wide common mode input range includes the 3 Channels - 33.9W RMS per package negative rail, facilitating single supply applications. IDEAL FOR SINGLE SUPPLY SYSTEMS This makes it possible to have a ground-based input 5V - Peripherals driving a single supply amplifier with ground acting as the second or bottom supply of the amplifier. 12V - Automotive 28V - Avionic PACKAGING OPTIONS 20-Pin PSOP, JEDEC MO-166-AB (PA162DK) +Vs I BIAS MONITOR +IN -IN OUT THERMAL PROTECT -Vs FIGURE 1.
