CROSS-REFERENCE ALTERNATIVE
COS8051SOT is a Chinese-manufactured 5V High-Speed Op-Amp from COSINE (科山芯创) that cross-references to AD8051ARTZ-REEL (ADI).
It is a SOT23-5 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.

COS8051SOT — 5V High-Speed Op-Amp, alternative to AD8051ARTZ-REEL
COS8051SOT is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for AD8051ARTZ-REEL (ADI). 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 COS8051SOT replace?
Every imported part number that COS8051SOT 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) |
|---|---|---|
| AD8051ARTZ-REEL | ADI | COS8051SOT |
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 COS8051SOT
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 at 5 V single supply and the input common-mode range available
- Slew rate, settling time and rise/fall time against the required edge speed
- Gain-bandwidth product and stability with capacitive loads — buffer with series R if needed
- Output current and swing at the load
- Input offset voltage and bias current
- Supply current and thermal dissipation in a small package
- Pinout, and whether the needed external compensation
Typical applications
- Video and fast ADC driver stages
- Active filters and anti-aliasing at 5 V
- Portable instrumentation and handheld test gear
- Photodiode and pulse amplification
- Communication and IF signal chains
- Fast DAC output buffers
