LM358DT Dual Operational Amplifier | STMicroelectronics SO-8 Low-Power Op Amp
A structured overview of LM358DT, including product introduction, key benefits, features, package information, pinout, specifications, equivalent reference, manufacturer information, and application guidance.
Product Introduction
LM358DT is a dual low-power operational amplifier from STMicroelectronics. It integrates two independent, high-gain, internally frequency-compensated operational amplifiers designed for single-supply operation across a wide voltage range.
The device is suitable for conventional operational amplifier circuits, transducer amplifiers, DC gain blocks, signal conditioning, and interface circuits where operation from a single power supply is preferred. Its input common-mode range includes the negative rail, making the LM358DT practical for low-side signal processing in single-supply systems.
Key Benefits
Low-power dual amplification
Two independent operational amplifiers are integrated into one device, helping simplify multi-channel analog signal conditioning circuits.
Wide single-supply operation
The LM358DT supports a supply voltage range of 3 V to 32 V, making it suitable for a variety of single-supply analog designs.
Ground-referenced input capability
The input common-mode voltage range includes the negative rail, which is useful when processing signals close to ground in single-supply circuits.
Compact SO-8 package
The SO-8 surface-mount package supports compact PCB layouts and common automated assembly processes.
Features
- Dual independent operational amplifiers in a single package.
- Internally frequency-compensated for stable operation in conventional amplifier configurations.
- Wide supply voltage range from 3 V to 32 V.
- Large DC voltage gain of 100 dB.
- Unity-gain bandwidth of 1.1 MHz with temperature compensation.
- Low input bias current of approximately 20 nA.
- Input common-mode voltage range includes the negative supply rail.
- Output voltage can swing close to ground when operated from a single supply.
- Industrial-grade LM358DT device supplied in an SO-8 package.
Package
The LM358DT is supplied in an SO-8 surface-mount package. STMicroelectronics lists the LM358DT as an active, volume-production product with an industrial grade classification.
The SO-8 package is commonly used for compact analog circuits and PCB-based signal conditioning designs. Designers should refer to the official STMicroelectronics datasheet for exact package dimensions, land pattern, thermal considerations, and soldering requirements.
Pinout
The LM358DT uses an 8-pin SO-8 configuration containing two independent operational amplifiers. The pin assignment should be verified against the latest official datasheet before PCB layout, prototyping, or production.
