Ordering number : ENN7558 Monolithic Digital IC LA6358AM High-Performance Dual Operational Amplifier Overview The LA6358AM is a high-performance dual operational amplifier that can operate from a single voltage power supply (3 to 24 V) and over a wide operating temperature range (-40 to 125°C). 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 LA6358AM can be used in a wide range of automotive and industrial applications as a transducer amplifier for all types of transducers, as a DC amplifier circuit, and for other purposes as well. Functions • Phase correction not required • Wide operating supply voltage range 3.0 V to 24.0 V (single power supply systems) ±1.5 V to 12.0 V (dual power supply systems) • The input voltage range extends to essentially the ground level, and furthermore the output voltage range for VOUT is from 0 V to VCC − 1.8 V. • Low current drain: ICC = 0.5 mA (typical) when VCC = +5 V, RL = ∞.
