LM358ADRG4

LM358ADRG4 Description

The LM358ADRG4 from Texas Instruments is a dual-channel general-purpose operational amplifier designed for a wide range of analog applications. Packaged in an 8-SOIC surface-mount format and supplied in Tape & Reel (TR), this IC operates over a 3V to 30V supply range, making it versatile for both low and moderate voltage systems. With a 700 kHz gain bandwidth product and a 0.3V/µs slew rate, it balances performance and power efficiency, drawing just 500µA per channel. The device features low input bias current (15 nA) and 2 mV input offset voltage, ensuring precision in signal conditioning. Though marked as obsolete, it remains ROHS3 compliant and REACH unaffected, suitable for legacy designs.
