Each of the four channels draws 950 nA typical, making the part suitable for battery-powered or energy-harvesting sensor interfaces, portable medical monitors, and remote IoT nodes that must run for years on a coin cell. The 16-QFN (3x3 mm) package saves board area in space-constrained designs. The listed package options — Tape & Reel and Cut Tape — cover both volume production and prototype quantities.","metaTitle":"STMicroelectronics TSU114IQ4T CMOS Op-Amp, 11.5 kHz","metaDescription":"TSU114IQ4T quad CMOS op-amp, 950 nA supply per channel, 11.5 kHz GBP, rail-to-rail output, 1.5 V to 5.5 V supply.

For a dual-channel option with similar low-power behavior, the TS942AIDT (10 kHz GBP, 0.0045 V/µs slew rate) is a close functional match in a smaller package."},{"question":"Does TSU114IQ4T have rail-to-rail output?","answer":"Yes, the output type is rail-to-rail, allowing the output to swing within millivolts of the supply rails. This maximizes dynamic range in low-voltage single-supply designs."},{"question":"What is the typical application of TSU114IQ4T?","answer":"Typical applications include battery-powered sensor interfaces (temperature, pressure, strain, electrochemical), portable medical devices, energy-harvesting IoT nodes, and any signal chain where supply current must stay under 1 µA per channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TSU114IQ4T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TSU114IQ4T when reusing this data.
