Its 90 kHz gain-bandwidth product and 0.05 V/µs slew rate place it firmly in the low-frequency signal conditioning role — think battery monitors, thermistor interfaces, photodiode amplifiers, and always-on sensor buffers where every microamp counts. The 8.6 µA supply current is the headline draw: at that level the part can run continuously from a coin cell without dominating the sleep budget. Rail-to-rail output preserves dynamic range at low supply voltages, and the 1.8 V minimum supply lets it operate directly from a single lithium cell or two alkaline cells. ## SOT-753 footprint — fits the tight board, but watch the thermal The BU7271SG-TR comes in the 5-pin SOT-753 package, also called SC-74A, with the supplier device package listed as 5-SSOP. This is the same footprint as the industry-standard SOT-23-5, so it drops onto existing pads without a layout change. The 8 mA output current per channel is modest — enough to drive a reference input or a low-power ADC, but not a heavy load. At 8.6 µA supply, self-heating is negligible, so the small package is not a thermal constraint in normal operation. Surface-mount assembly is standard; no exposed pad to worry about.","metaTitle":"ROHM BU7271SG-TR General Purpose Op-Amp, 90 kHz GBW, 5-SSOP","metaDescription":"ROHM BU7271SG-TR general-purpose op-amp: 90 kHz GBW, 8.6 µA supply, rail-to-rail output, 1.8 V to 5.5 V supply, -40°C to 105°C, SOT-753.

The BU7271SG-TR is a functional alternative if the circuit can tolerate the lower bandwidth (90 kHz vs typically 1 MHz for the LMV321) and the 8.6 µA supply is acceptable. Pin compatibility depends on the specific LMV321 variant — some have different pinouts — so verify the pin mapping against the datasheet before placing the part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/BU7271SG-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/BU7271SG-TR when reusing this data.
