Ordering number : ENN2704C LA6324N Monolithic Linear IC High-Performance Quad Operational Amplifier http://onsemi.com 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 720 V mW Operating temperature Topr -30 to +85 °C Storage temperature Tstg -55 to +125 °C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
