Its 9 kHz gain-bandwidth product and 650 nA supply current per channel place it in the nano-power class, suitable for always-on sensor conditioning, battery monitoring, and portable instrumentation that must run for years from a coin cell or single-cell alkaline battery. The rail-to-rail output stage preserves dynamic range at low supply voltages, and the 1 pA typical input bias current allows direct interfacing with high-impedance sources such as photodiodes, pH probes, and piezoelectric sensors without an external buffer. ## Supply range and single-supply operation The 1.5 V minimum means it runs directly from a single alkaline cell (nominal 1.5 V) or a NiMH cell (1.2 V with headroom), eliminating the need for a boost converter in single-cell designs. The 5.5 V maximum covers two-cell alkaline, standard 3.3 V regulated rails, and 5 V logic supplies. The rail-to-rail output swings within millivolts of both rails, which is critical for maximizing ADC input range or driving a comparator threshold when the supply is only 1.5 V. This part is fully specified for single-supply operation across the entire voltage range. ## Package and temperature grade The 14-TSSOP package and ROHS3 compliance suit standard surface-mount assembly and current regulatory requirements. ## Sourcing and lifecycle posture The ROHS3 compliance is current for global markets including EU and UKCA jurisdictions. ## Output drive and slew rate Each of the four channels can source or sink 11 mA of output current, which is sufficient to drive a reference input, a small LED indicator, or the analog input of a low-power ADC. The slew rate of 0.003 V/µs is consistent with the 9 kHz GBW — this is a slow amplifier by design. It is not intended for audio, fast ADC driving, or any signal path above a few hundred hertz. The low slew rate also contributes to the nano-power budget by limiting internal charging currents.","metaTitle":"STMicroelectronics TSU104IPT CMOS Op-Amp, 9 kHz GBW","metaDescription":"ST TSU104IPT quad CMOS op-amp: 9 kHz GBW, 650 nA supply per channel, 1.5–5.5 V supply, rail-to-rail output, 1 pA bias.

The TSU104IPT operates from a single supply as low as 1.5 V and as high as 5.5 V. The rail-to-rail output swings close to both supply rails, making it suitable for single-supply circuits where the signal ground is at the negative rail."},{"question":"What is the closest functional equivalent to TSU104IPT?","answer":"The TS942AIDT is a dual-channel CMOS op-amp with a 10 kHz GBW and similar 1 pA input bias current, but it has only two channels versus four, and its supply voltage minimum is 2.5 V versus 1.5 V. For a quad-channel replacement, the TS274IPT offers 3.5 MHz GBW but draws 1 mA per channel — a 1500× increase in supply current. The TSU104IPT is unique in combining quad channels, 650 nA per channel, and 1.5 V operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TSU104IPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TSU104IPT when reusing this data.
