Monolithic Linear IC
High-Performance
Dual Operational Amplifiers
Overview
The LA6358 is a high-performance dual operational amplifier that can operate from a single voltage power supply.
It features a built-in phase correction circuit. It can also operate from a dual power supply with both positive and negative
levels and features low power consumption. The LA6358NT can be used in a wide range of industrial applications as a
transducer amplifier for all types of transducers, as a DC amplifier circuit, and for other purposes as well.
Functions
Eliminates need for phase compensation
Wide range of operating supply voltage: 3.0V to 30.0V (single power supply)
: ±1.5 to ±15.0V (dual power supply)
Input voltage swingable down to nearly ground level and output voltage range VOUT of 0 to VCC-1.5V
Low current dissipation : ICC = 0.5mA typ/VCC = +5V, RL =
