CROSS-REFERENCE ALTERNATIVE
COS324SR is a Chinese-manufactured General-Purpose Op-Amp from COSINE (科山芯创) that cross-references to LMV324IDR (TI).
It is a SOP14 device positioned as a domestic-supply option against the imported: shorter lead times, no allocation risk and a stable price for volume production. Because the parts are not pin-identical in every case, the engineering checklist below lists what to verify before you commit.

COS324SR — General-Purpose Op-Amp, alternative to LMV324IDR
COS324SR is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for LMV324IDR (TI). Imported parts in this class are frequently subject to allocation, long lead times and steep price swings. A Chinese-manufactured equivalent removes that exposure: the parts are production-validated in industrial, consumer and automotive designs and ship from stock on a short lead time.
Cross-reference chart — which imported parts does COS324SR replace?
Every imported part number that COS324SR is published as a cross-reference alternative to, per the COSINE (科山芯创) 2025 selection table:
| imported part number | brand | Replaced by (this part) |
|---|---|---|
| LMV324IDR | TI | COS324SR |
Cross-reference means functional equivalence in the same application role. It is not a blanket claim of pin-for-pin identity — confirm package, pinout and the parameters listed below before you release a design change.

What to verify before substituting COS324SR
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Supply range including single-supply operation
- Gain-bandwidth product and slew rate for the signal bandwidth
- Output swing and drive capability into your load
- Input common-mode range, including whether ground sensing is needed
- Input offset voltage and bias current tolerance
- Quiescent current and package thermal behaviour
- Package/pinout for single, dual and quad
Typical applications
- General analogue signal conditioning
- Active filters and buffers
- Comparator-adjacent threshold circuits
- Level shifting and summation
- Consumer and industrial control boards
- Sensor and transducer interfaces
