The 14-TSSOP package ships in Tape & Reel (2500/reel) or Cut Tape options, suitable for both volume assembly and prototype builds. ## Hand-soldering the 14-TSSOP footprint Use a stencil for solder paste if you're placing more than a handful; the 0.173-inch body length is forgiving for alignment under a magnifier.","metaTitle":"OPA4344EA/250 Quad CMOS Op-Amp, 1 MHz, Rail-to-Rail Output","metaDescription":"TI OPA4344EA/250 quad CMOS op-amp: 1 MHz GBW, 0.8 V/µs slew rate, 150 µA/ch supply, rail-to-rail output, 14-TSSOP.

For a lower-power alternative, the OPA4344 itself is hard to beat at 150 µA per channel. No pin-compatible second source is listed, so verify the footprint if substituting."},{"question":"Can OPA4344EA/250 be used as a replacement for LM324?","answer":"In many general-purpose signal conditioning roles, yes — the OPA4344EA/250 offers lower supply current (150 µA vs ~500 µA per channel for LM324), rail-to-rail output, and much lower input bias current (0.2 pA vs ~100 nA). However, the LM324 operates from a wider supply range (up to 32 V) and has a higher output current capability. Check your supply voltage and output drive requirements before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA4344EA-250","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA4344EA-250 when reusing this data.
