PIN-TO-PIN ALTERNATIVE
SGM8544XS is a Chinese-manufactured pin-to-pin drop-in replacement for LM324 (Texas Instruments / STMicroelectronics).
Quad rail-to-rail cross-reference for LM324 designs running on a single low-voltage rail.
SGM8544XS — Alternative to LM324
SGM8544XS from SGMicro {BRAND} is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported LM324 (Texas Instruments / STMicroelectronics). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.

What to check before substituting SGM8544XS for LM324
- Pin-to-pin with LM324 in SOIC-14, so the footprint is unchanged.
- Narrow 2.1 V to 5.5 V supply range - verify your rail before substituting a 12 V or 24 V LM324 design.
- Rail-to-rail I/O and pico-amp bias current in a quad package, for multichannel single-supply sensing.
Typical Applications
- Multichannel sensor signal conditioning
- Portable instruments
- Active filters and summing amplifiers
- Battery-powered control systems
