Product Overview
Motorola LM358N. Dual low power operational amplifier in an 8-pin DIP package. Two independent, internally frequency-compensated op-amps in one IC, designed to run from a single supply across a wide voltage range - no split rail required. Date code 9647 visible on the package.
Key Features
- Dual op-amp: two independent channels in one DIP-8 package
- Single-supply operation: 3V to 32V
- Dual-supply operation: ±1.5V to ±16V
- DC voltage gain: 100 dB
- Unity gain bandwidth: 1.1 MHz
- Low supply current: 500 µA typical, essentially independent of supply voltage
- Input common-mode range includes ground
- Input offset voltage: 2 mV typical
- Input bias current: 20 nA typical
- DIP-8 package - breadboard and through-hole friendly
Applications
- Hobbyist drops this into a breadboard to prototype a sensor interface or voltage follower in minutes - no dual supply needed, just a single battery or bench supply
- Repair tech pulls a failed op-amp from a consumer or industrial board and drops in the LM358N as a direct replacement without redesigning the surrounding circuit
- Embedded developer uses it to condition a weak sensor signal before feeding it to a microcontroller ADC, keeping quiescent current low to extend battery life
- Electronics student wires up inverting, non-inverting, integrator, and differentiator configurations on a breadboard to work through op-amp fundamentals hands-on
- Maker builds a simple audio preamp, light-sensing circuit, or DC gain block for a custom project where the DIP footprint and single-supply simplicity matter more than high bandwidth
Frequently Asked Questions
Is this the DIP-8 through-hole package?
Yes. Photo confirms a standard DIP-8 black plastic package with eight unbent leads - fits a breadboard or through-hole PCB footprint directly.
What power supply does it need?
Single supply from 3V to 32V, or dual supplies from ±1.5V to ±16V. No split rail required for single-supply circuits.
Can it be used as a comparator?
It can be pressed into comparator duty in low-speed, non-critical applications, but the output does not swing rail-to-rail and the slew rate is 0.3 V/µs typical - not suited for precise or fast digital signal comparison.
Will this drop in as a replacement for other LM358N chips from different manufacturers?
The LM358N is a widely second-sourced part. This is a Motorola-marked unit. For precision-critical applications, confirm parameters against the specific manufacturer's datasheet for your design.
A 1996 Motorola fab, pins still straight, waiting on the bench. Whatever you are building or fixing, this one has been patient.
