CROSS-REFERENCE ALTERNATIVE
COS722SR is a Chinese-manufactured Low-Noise Op-Amp from COSINE (科山芯创) that cross-references to LMV722IDR (TI).
It is a SOP8 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.

COS722SR — Low-Noise Op-Amp, alternative to LMV722IDR
COS722SR is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for LMV722IDR (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 COS722SR replace?
Every imported part number that COS722SR 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) |
|---|---|---|
| LMV722IDR | TI | COS722SR |
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 COS722SR
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Input voltage noise density at the frequency your signal occupies, plus the 1/f corner
- Current noise and its contribution across the source impedance — the reason a low-voltage-noise part can still be wrong here
- Gain-bandwidth product and closed-loop bandwidth
- Total harmonic distortion at the output amplitude you need
- Input bias current and offset voltage
- Output drive into the real load
- Package and pinout, and any required supply decoupling
Typical applications
- Audio preamplifiers and microphone front ends
- Sensor and transducer interfaces
- PLL loop filters and VCO control
- Precision instrumentation
- Photodiode and low-level signal amplification
- Communication receive paths
