Automotive ICs

Automotive, 125°C Operation, ±0.1%, 20 ppm/°C, Low noise, High-Precision Shunt Voltage Reference S-19760 Series

Maximum shunt current : 15 mA (S-19760) | 30 mA (S-19761)

This IC is high-precision, low temperature coefficient, and low output noise shunt voltage reference developed using CMOS process technologies and is available in SOT-23-3 and compact HSNT-8(1616)B packages. Power can also be supplied from a high input voltage by selecting an appropriate external shunt resistor, making it possible to generate high-precision system reference voltage. The output voltage (reverse breakdown voltage) can be selected from 6 internally fixed voltages of 2.048 V, 2.5 V, 3.0 V, 3.3 V, 4.096 V, or 5.0 V.
This IC is available in 3 accuracy types. A type has an output voltage accuracy of ±0.1% and output voltage temperature coefficient of 20 ppm/°C max. (Ta = -40°C to +125°C).
The IC is compatible with a wide range of shunt currents with a maximum shunt current of 15 mA.

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.
