The rail-to-rail output lets it swing within millivolts of the supply rails, so you get the full ADC input range without a second gain stage. ## 14 kHz GBWP, 0.003 V/µs slew rate Gain-bandwidth product is 14 kHz and slew rate is 0.003 V/µs. That combination means this op amp is for DC or very slow signals — think thermocouple conditioning, photodiode current sensing, or battery voltage monitoring. It will not track audio or motor encoder edges. ## Active production, 8-SOIC package Status is Active, ROHS3 compliant. The 8-SOIC (0.154\", 3.90 mm width) package is a standard footprint — hand-solderable with a fine tip, and widely supported by breakout boards. Supplied in Tube; if you need Tape & Reel for pick-and-place, check the MCP6043T-I/SN variant or request a quote for the tube-to-reel conversion. ## 1 pA input bias, 3 mV offset Input bias current is 1 pA — negligible for high-impedance sources like pH probes or pyroelectric sensors. Input offset voltage is 3 mV typical; for a single-supply 3.3 V system that is about 0.09% of the rail, acceptable for most 8-10 bit measurements without auto-zero.","metaTitle":"MCP6043-I/SN Op Amp – 600 nA, Rail-to-Rail, 8-SOIC","metaDescription":"Microchip MCP6043-I/SN general-purpose op amp: 600 nA supply, 14 kHz GBWP, rail-to-rail output, 8-SOIC.

The rail-to-rail output preserves dynamic range at low supply voltages."},{"question":"Does MCP6043-I/SN have a shutdown function?","answer":"The evidence does not list a shutdown pin or enable feature. For a micropower op amp with shutdown, consider the MCP6041 family (same 600 nA quiescent, plus SHDN)."},{"question":"What is the closest functional second-source to MCP6043-I/SN?","answer":"Within Microchip's portfolio, the MCP6142T-I/SN is a dual-channel op amp with similar 600 nA per channel supply and rail-to-rail output, but it offers 100 kHz GBWP and 0.024 V/µs slew rate — faster than the MCP6043. If you need a single-channel drop-in with higher bandwidth, the MCP6291T-E/MS (10 MHz, 7 V/µs) draws 1 mA, so it is not a low-power substitute."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MCP6043-I-SN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MCP6043-I-SN when reusing this data.
