LM2904ITP/NOPB

The LM158 series comprises two independent high-gain internally frequency-compensated operational amplifiers, specifically designed for operation with a single power supply over a wide voltage range. They can also be powered by split power supplies, and the low supply current consumption is independent of the supply voltage level. Application areas include sensor amplifiers, DC gain blocks, and all conventional operational amplifier circuits, which can now be easily implemented in single-supply systems. For example, the LM158 series can operate directly from the standard 3.3 V supply voltage used in digital systems and can readily provide the required interface electronics without the need for an additional ±15 V power supply.
