Product No: WEAOPSPLO18PI18RO12M22GDownload Datasheet

  • Applications:Temperature Sensors
  • Maturity:GDS Ready
  • Foundry:GF
  • Geometry (nm):22nm
  • Process Node:22FDX

The WEAOPSPLO18PI18RO12M22G is a special purpose low offset buffer for bias generator that provides a buffered ouput for the Temperature Sensor. The OpAmp deliberately exhibits systematic offsets to favor near zero Output Voltages. It is Ideal for Temperature sensors with Rail – To – Rail Output that can go down to zero values.
