LM358DT Low-Power Dual Op Amp | SOIC-8 General-Purpose Amplifier | STMicroelectronics

LM358DT

Low-power analog IC integrating two independent high-gain op amps, operating from a single 3 V–30 V supply or dual ±1.5 V–±15 V supplies, with input common-mode range including ground, 1.1 MHz unity-gain bandwidth and about 0.6 V/µs slew rate, ideal for sensor signal conditioning, power monitoring, and general-purpose analog front ends.

Product Description

Product Overview

The LM358DT from STMicroelectronics is a low-power dual operational amplifier featuring two independent, internally frequency-compensated high-gain op-amps designed for operation over a wide range of supply voltages, especially optimized for single-supply systems.

With an input common-mode range including the negative rail and an output swing from 0 V up to approximately (VCC – 1.5 V), it can amplify and buffer low-side signals in 5 V logic systems without requiring a negative supply.

Packaged in an SOIC-8 (SO8) outline, the device typically draws about 0.5–0.7 mA per channel, keeping total supply current in the ~1–1.2 mA range, making it attractive for low-power and cost-sensitive analog designs.
