COSINE (科山芯创) builds a broad analog IC line that covers most of what a mixed-signal board needs: amplifiers, drivers, regulators, references, comparators, switches and interfaces. This guide is a single map of that family, with one representative part from each group we stock, so you can plan a bill of materials around COSINE and still cross-reference the industry references you already know.

How to plan a COSINE analog BOM
- Group the board by function: sense, amplify, drive, regulate, switch, interface.
- Pick one family per function from the table above, then widen to the specific package and channel count you need.
- For each part, send the original industry reference and we will match the COSINE equivalent.
- Note that power-line carrier parts are not yet stocked — ask us to source them specifically.
Explore the full amplifiers and data conversion range and the power management range. Send us your bill of materials and we will quote the COSINE lines we can supply, with date codes and availability.
Frequently asked questions
Which COSINE analog family should I start with?
Start from the function, not the part number: precision measurement points to zero-drift op-amps and instrumentation amplifiers; power switching points to MOSFET and high-voltage gate drivers; power rails point to LDOs and references. This guide is a map of the whole COSINE analog IC family we stock.
Do you stock COSINE parts for hard-to-find references?
Yes. Many COSINE parts are offered as alternatives to widely used references such as OPA, INA, LMV, TC44xx, IRS2xxx, MIC29xxx, TLVH43x, UC3842 and TJA1042. Send us the original part number and we will match the COSINE equivalent with package and date code.
What about power-line carrier (PLC) parts?
Power-line carrier transceivers are not yet part of our stocked COSINE line. If you need them, tell us the exact part and we will source against availability — otherwise use the families below as the core of an analog bill of materials.
Are these COSINE parts drop-in replacements?
They are designed against the pinout and function of the referenced devices. Confirm package, pinout and electrical limits on the datasheet for your application before volume commitment.
