TLV2221IDBVT

Texas Instruments · Operational Amplifier · SOT-23-5

TLV2221IDBVT from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Output terminal, which swings rail-to-rail because the output swing includes both supply rails.
2 VDD−/GND power_in Negative supply rail, which serves as GND in single-supply operation (supply range 2.7 V to 10 V).
3 IN+ input Noninverting input whose common-mode input voltage range includes the negative rail.
4 IN− input Inverting input whose common-mode input voltage range includes the negative rail; it sits on the same board end as OUT to provide negative feedback.
5 VDD+ power_in Positive supply rail; the device operates over a wide supply range of 2.7 V to 10 V.
