CROSS-REFERENCE ALTERNATIVE
COS4182UA is a Chinese-manufactured 36V Zero-Drift Precision Op-Amp from COSINE (科山芯创) that cross-references to OPA4182 (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.

COS4182UA — 36V Zero-Drift Precision Op-Amp, alternative to OPA4182
COS4182UA is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for OPA4182 (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 COS4182UA replace?
Every imported part number that COS4182UA 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) |
|---|---|---|
| OPA4182 | TI | COS4182UA |
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 COS4182UA
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Offset voltage and drift at 36 V operation, not just at 5 V
- Input common-mode range at the high rail under a 36 V supply
- Input bias current vs the bipolar part across the full temperature range
- Noise density and chopping artefacts at your signal bandwidth
- Output drive capability and load regulation
- Thermal behaviour and quiescent current at the high supply voltage
- Package, pinout and compensation
Typical applications
- Industrial precision measurement at 24 V rails
- High-side current sensing in motor drives
- Bridge transducers in process control
- Loop-powered 4–20 mA instruments
- Battery management and energy metering
- Precision power-supply feedback
