Description
POWER DUAL OPERATIONAL AMPLIFIERS PA21/25/26 PA21A/25A M I C R O T E C H N O L O G Y HTTP://WWW.APEXMICROTECH.COM (800) 546-APEX (800) 546-2739 FEATURES LOW COST WIDE COMMON MODE RANGE — Includes negative supply WIDE SUPPLY VOLTAGE RANGE Single supply: 5V to 40V Split supplies: ±2.5V to ±20V HIGH EFFICIENCY — |Vs–2.2V| at 2.5A typ HIGH OUTPUT CURRENT — 3A min (PA21A) INTERNAL CURRENT LIMIT LOW DISTORTION R2 9K +28V R1 5K + 1/2 PA21 COMMAND INPUT 0/10V – A M R3 10K R4 10K – B + 1/2 PA21 R5 10K +28V APPLICATIONS HALF & FULL BRIDGE MOTOR DRIVERS AUDIO POWER AMPLIFIER STEREO — 18W RMS per channel BRIDGE — 36W RMS per package IDEAL FOR SINGLE SUPPLY SYSTEMS 5V — Peripherals 12V — Automotive 28V — Avionic R6 10K FIGURE 1: BIDIRECTIONAL SPEED CONTROL FROM A SINGLE SUPPLY The amplifiers are especially well-suited for this application. The extended common mode range allows command inputs as 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 0V to 10V 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. DESCRIPTION The amplifiers consist of a monolithic dual power op amp in a 8-pin hermetic TO-3 package (PA21 and PA25) and a 12pin SIP package (PA26)....
