PA75 RoHS Dual Power Operational Amplifiers COMPLIANT FEATURES RoHS Compliant Low Cost Wide Bandwidth - 1.1 MHz High Output Current - 2.5A (Combined) 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 APPLICATIONS Half And Full Bridge Motor Drivers Audio Power Amplifier Ideal for Single Supply Systems 5V Peripherals, 12V Automotive, 28V Avionic PACKAGING OPTIONS 7 TO-220 Plastic Package (PA75CD) 7 TO-220 with Staggered Lead Form (PA75CX) 7 DDPAK Surface Mount Package (PA75CC) DESCRIPTION The amplifier design consists of a dual power op amp on a single monolithic die. Side B of the dual mono- lithic is configured as a unity gain buffer to increase the current capability of the primary side A. The use of two PA75 amplifiers provides a cost-effective solution to applications where multiple amplifiers are required or a bridge configuration is needed. Very low harmonic distortion of 0.02% THD and low I makes the PA75 a Q good solution for power audio applications. The PA75 is available in three standard package designs. The surface mount version of the PA75, the PA75CC, is an industry standard non-hermetic plastic 7-pin DDPAK. The through hole versions of the PA75, the PA75CD and PA75CX, are industry standard non-hermetic plastic 7-pin TO-220 packages. The PA75CX is staggered lead formed and offers standard 100 mil spacing. This allows for easier PC board layout. (Please refer to the CX lead form package drawing for dimension of the PA75CX). The monolithic amplifier is directly attached to the metal tabs of the PA75CC, PA75CD, and PA75CX. The metal tabs of the packages are directly tied to -Vs. Apex Microtechnology Inc.
