CROSS-REFERENCE ALTERNATIVE
COSLM13700SR is a Chinese-manufactured Transconductance (OTA) Amplifier from COSINE (科山芯创) that cross-references to LM13700 (TI).
It is a SOP16 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.

COSLM13700SR — Transconductance (OTA) Amplifier, alternative to LM13700
COSLM13700SR is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for LM13700 (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 COSLM13700SR replace?
Every imported part number that COSLM13700SR 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) |
|---|---|---|
| LM13700 | TI | COSLM13700SR |
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 COSLM13700SR
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Transconductance (gm) and its linearity vs the control current Iabc — and the gm scaling constant the design assumes
- Maximum control current and the corresponding upper gm limit
- Buffer/darlington output stage availability and its offset voltage
- Linearizing diode pins, and whether the design used them
- Supply range and dual-supply operation
- Package and pinout — the buffer pins are usually the ones that differ
Typical applications
- Voltage-controlled filters and VCOs
- AGC and gain-control loops
- Programmable amplifiers and multipliers
- Analogue multipliers and modulators
- Electronic attenuators
- Class-AB buffer and current-source circuits
