Temperature Sensor IC S-8110C/8120C Series

The S-8110C/8120C Series is a family of high-precision temperature sensor ICs on a single chip with a linear
output voltage for temperature changes.
Each chip is composed of a temperature sensor, a constant current circuit, and an operational amplifier.
It can be used at temperatures ranging from -40°C to +100°C. These devices have much better linearity than
other temperature sensors such as thermistors, and can be used for a wide range of temperature control

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
