AD8551-TD

TDSEMIC · Precision Op Amps · SOT-23-5L

AD8551-TD from TDSEMIC, in a SOT-23-5L. 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 Amplifier output.
2 -VS power_in Negative (lowest) power supply.
3 +IN input Non-inverting input of the amplifier; absolute maximum signal input range is VS- - 0.5 V to VS+ + 0.5 V, ±20 mA.
4 -IN input Inverting input of the amplifier; absolute maximum signal input range is VS- - 0.5 V to VS+ + 0.5 V, ±20 mA.
5 +VS power_in Positive (highest) power supply, 1.8 V to 5.5 V operating range and 10.0 V absolute maximum between VS+ and VS-.
