This selection map groups the COSINE (科山芯创) precision operational amplifiers we stock by the job they do best. COSINE is a third-party brand; Jingteng Electronics is an independent distributor and these references are for identification and compatibility engineering only.
Zero-drift — lowest offset & drift
For DC and slow sensor paths where offset dominates: COS8552, COS4333 and the wider COS2388/COS2376/COS2180 families (5 V to 36 V).
Low-noise — best for AC and audio
COS724, COS722, COS721 and COS2374 for clean signal amplification where white and 1/f noise must stay low.
Micro-power — longest battery life
COS6002, COS9001, COS9041 and COS6054 draw nanoamp-scale quiescent current for portable and energy-harvesting gear.
Rail-to-rail & high-speed
Rail-to-rail general-purpose parts such as COS358 and COS324; high-speed devices COS8052, COS8091 and COS8042 for wideband and video-class paths.

Alternative & Cross-Reference Parts (for reference)
The devices below are commonly used industry parts in the same functional class. They are listed for identification and compatibility-engineering reference only. A cross-reference is not a guarantee of pin-to-pin or 100% functional equivalence — package, pinout, electrical parameters and temperature drift can differ between devices. Always verify against the original manufacturer's datasheet before substituting any part.
| Manufacturer | Typical part(s) | Class / note |
|---|---|---|
| Industry class | Zero-drift | Comparable to AD855x / OPA333 families |
| Industry class | Low-noise | Comparable to OPA211 / AD797 families |
| Industry class | Micro-power | Comparable to LPV801 / AD850x families |
| Industry class | Rail-to-rail | Comparable to TLV237x / AD860x families |
| Industry class | High-speed | Comparable to OPA350 / ADA4807 families |

Frequently Asked Questions
How should I pick a COSINE op-amp?
Start from the signal, not the brand: decide whether you need lowest offset (zero-drift), lowest noise (low-noise), lowest current (micro-power), rail-to-rail swing, or highest speed, then pick within that group for the right supply and package.
Are these alternatives to specific industry parts?
Many map to common industry devices by function and package. Treat any cross-reference as a compatibility starting point — confirm pinout, parameters and the original datasheet before substituting in a design.
Can Jingteng supply date code and quantity?
As an independent distributor we confirm availability, pricing and date code at quotation. For hard-to-find or end-of-life parts, ask early so we can source through verified channels.
