LM1458 LM1558 Dual Operational Amplifier IC

The LM1458 and LM1558 are general-purpose dual operational amplifier ICs designed for low-power analog signal applications. Each IC contains two independent op-amps with a shared bias and power supply, offering stable performance without the need for external frequency compensation. These devices support wide common-mode and differential voltage ranges, making them ideal for laptop analog circuits, power sensing, audio filtering, and instrumentation. LM1558 supports an extended temperature range, while LM1458 is optimized for commercial temperature operation.
