Ordering number : ENN2704C Monolithic Linear IC LA6324N LA6324NM High-Performance Quad Operational Amplifier Overview The LA6324 consists of four independent, high-performance, internally phase compensated operational amplifiers that are designed to operate from a single power supply over a wide range of voltages. These four operational amplifiers are packaged in a single package. As in case of conventional general-purpose operational amplifiers, operation from dual power supplies is also possible and the power dissipation is low. It can be applied to various uses in commercial and industrial equipment including all types of transducer amplifiers and DC amplifiers. Features • No phase compensation required • Wide operating voltage range: 3.0 V to 30.0 V (single supply) ±1.5 V to ±15.0 V (dual supplies) • Highly resistant to dielectric breakdown • Input voltag range includes the neighborhood of GND level and output voltage range VOUT is from 0 to VCC –1.5 V. • Small current dissipation: ICC = 0.6 mA typ/VCC = + 5 V, RL = ∞ Specitications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum Supply voltage VCC max 32 V Differential input voltage VID 32 V Maximum input voltage VIN max Allowable power dissipation Pd max -0.3 to +32 LA6324N LA6324NM V 720 mW 330 mW Operating temperature Topr -30 to +85 °C Storage temperature Tstg -55 to +125 °C Any and all SANYO Semiconductor products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.
