CROSS-REFERENCE ALTERNATIVE
COS6112 is a Chinese-manufactured Audio Power Amplifier from COSINE (科山芯创) that cross-references to TPA6112A2 (TI), and also to SGM4812.
It is a MSOP10 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.

COS6112 — Audio Power Amplifier, alternative to TPA6112A2
COS6112 is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for TPA6112A2 (TI), SGM4812 (圣邦微). 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 COS6112 replace?
Every imported part number that COS6112 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) |
|---|---|---|
| TPA6112A2 | TI | COS6112 |
| SGM4812 | 圣邦微 | COS6112 |
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 COS6112
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Output power delivered into your load impedance at your supply voltage
- Gain setting and the external gain-set network
- Supply range and single-supply operation with mid-rail biasing
- Shutdown and mute pin behaviour and their logic polarity
- Total harmonic distortion plus noise at the output level you need
- Protection features: thermal, short-circuit and pop/click suppression
- Package and pinout
Typical applications
- Portable speakers and Bluetooth audio
- Headphone and earbud amplifiers
- Handheld instruments with audio output
- Toys and consumer audio products
- Intercom and voice-announcement systems
- Laptop and monitor audio
