Each of the four channels draws 10 µA, making the total quiescent current 40 µA for the entire package. The gain bandwidth product is 100 kHz with a slew rate of 0.04 V/µs, which places this part firmly in the domain of DC and low-frequency signal conditioning — think thermocouple amplifiers, strain-gauge bridges, battery-voltage monitoring, and photodiode front ends where the signal changes slowly. Input bias current is 1 pA, so it does not load high-impedance sources. The 14-SOIC (3.90 mm width) package is a standard JEDEC outline, so PCB layout is straightforward and second-source footprints are widely available. The ROHS3 compliance covers the current EU directive without exemptions. ## What the 0.04 V/µs slew rate means for the BOM A slew rate of 0.04 V/µs limits the large-signal bandwidth to roughly 6.4 kHz at 1 V peak output. This is not a part for audio line drivers, switching power-supply error amplifiers, or any loop that must settle quickly. It is, however, perfectly adequate for filtering and amplifying DC-coupled sensor outputs where the signal of interest changes at a few hertz to a few hundred hertz. The 100 kHz gain bandwidth supports closed-loop gains up to about 100 before the -3 dB point drops below 1 kHz. If your design needs to pass a 10 kHz square wave cleanly, look at a faster CMOS op-amp like the TS274 (3.5 MHz GBW, 5.5 V/µs slew rate) — but that part draws 1 mA per channel, 100× the supply current. ## Output drive and input offset Each channel can source or sink 45 mA, which is generous for a micropower op-amp and enough to drive a 2 kΩ load to within a volt of the rails. Input offset voltage is specified at 900 µV maximum — not precision territory, but acceptable for general-purpose sensor interfaces where the signal is several millivolts or more. The CMOS input stage gives the 1 pA bias current, so source impedance up to 1 MΩ does not create a significant voltage error.","metaTitle":"STMicroelectronics TS27L4AIDT CMOS Quad Op-Amp, 100 kHz","metaDescription":"ST TS27L4AIDT quad CMOS op-amp: 100 kHz GBW, 0.04 V/µs slew rate, 10 µA supply per channel, 1 pA bias, -40°C to 125°C, 14-SOIC.

The CMOS output stage can swing close to the rails with a light load, but the input common-mode range does not include the positive rail. For true rail-to-rail operation, a different amplifier family would be needed."},{"question":"What is the power consumption of TS27L4AIDT?","answer":"Each of the four channels draws 10 µA of supply current, so the total quiescent current for the package is 40 µA. At a 5 V supply, that is 200 µW total quiescent power. This is the defining characteristic of the part — it is designed for battery-powered and energy-harvesting applications where every microamp is budgeted."},{"question":"Can TS27L4AIDT replace TS27L4AID?","answer":"The TS27L4AIDT and TS27L4AID are the same silicon in the same 14-SOIC package; the 'T' suffix typically denotes tape-and-reel packaging. Electrically they are identical. The TS27L4AIDT is the tape-and-reel variant, which is the standard ordering code for volume production. If your BOM calls for TS27L4AID, the TS27L4AIDT is a direct substitute."},{"question":"What is the equivalent or replacement for TS27L4AIDT?","answer":"For a faster alternative with higher supply current, the TS274 offers 3.5 MHz GBW and 5.5 V/µs slew rate at 1 mA per channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TS27L4AIDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TS27L4AIDT when reusing this data.
