Product Overview
Unused NOS Dual Op Amp in SOIC-8 Package
This dual operational amplifier supports common amplification and buffering roles in control and signal paths, making it useful for circuit repair or prototyping work. The compact SOIC-8 format helps in drop-in replacement or SMD-to-through-hole adapter use, and a simple tip is to confirm pin-1 orientation before soldering during install/repair.
Product Condition
Unused, New Old Stock.
Product Overview
This device is a generic 358-series dual operational amplifier in an SOIC-8 surface-mount package. The family is widely recognized for single-supply operation and stable low-power behavior in general-purpose analog stages. Markings indicate a 358 top code and 823A underside code. It is suited for amplification, buffering, filtering, and analog interfacing tasks.
Key Features
- Dual op amp functional block for general-purpose analog work
- SOIC-8 SMD package for compact layouts
- Typical single-supply operation within 358-series norms
- Compatible with many 358 pinouts from multiple manufacturers
- Top marking “358” with underside code “823A”
- Useful for low-level signal conditioning stages
- Suitable for breadboard adapters or small PCB modules
- Supports common buffering and filtering topologies
Applications
- Analog signal amplification stages
- Sensor interface and conditioning circuits
- General-purpose buffering tasks
- Active filter and comparator-style configurations
- Prototype boards and repair of existing SMD assemblies
- Educational or lab analog electronics projects
Frequently Asked Questions
Is this compatible with common 358 pinouts?
Yes. The SOIC-8 layout follows typical 358-series conventions used across many manufacturers.
Can it be used on single-supply designs?
Yes. 358-family devices are frequently applied in single-supply analog circuits.
What do the markings 358 and 823A indicate?
The 358 top code designates the amplifier family; 823A is an underside lot or internal code.
Is the exact manufacturer known?
No manufacturer identifier appears on the marking, so compatibility is evaluated at the 358-family level.
Use this device in sensor interface circuits while applying the dual op amp block noted in Key Features, placing it onto a PCB or adapter during repair or prototyping work.
