COSINE Op-Amp and Power Selection Guide (5-Part Comparison)
JARWEY’s COSINE portfolio already includes several op-amp and power devices with public datasheets for evaluation. This guide puts five core parts in one table so engineering and sourcing can quickly decide among zero-drift, instrumentation, wide-supply precision amps, high-current LDOs, and HPLC line drivers.
Five-part comparison
| Part | Type | Package | Cross-ref | Page |
|---|---|---|---|---|
| COS8552SR | Zero-drift op amp | SOP-8 | AD8552 | 865 |
| COS620BRZ | Instrumentation amp | SOP-8 | INA129 / AD620 | 864 |
| COS4177SR | HV precision op amp | SOP-14 | OPA4277 / OPA4202 | 866 |
| COS29752WU | High-current PMIC/LDO | TO-263-5 | MIC29752 | 863 |
| COS6212Q24R | HPLC line driver | QFN-24-EP | THS6222 / THS6212 | 862 |
Quick path by use case
Battery wearables / tiny DC / drift-sensitive → COS8552SR.
ECG / bridges / high CMRR → COS620BRZ.
BMS/servo wide-supply precision & current sense → COS4177SR.
AI/auto high-current post-reg → COS29752WU.
Smart-meter HPLC line drive → COS6212Q24R.
Second-source checklist
1) Pick category + cross-ref from the table; 2) download datasheets for package/supply/key AC-DC specs; 3) pilot for drift, noise, transient or line distortion; 4) lock lead time/packaging before BOM release.
