Reference Design for Low-noise Precision Variable Voltage Reference


Design files


TIPD194 is a precision dynamic voltage reference source that is able to supply a voltage range from of ±10 V with a 16-bit resolution focusing on initial accuracy and low noise.

  • ±10 V output range
  • Less than 0.02 %FSR initial accuracy
  • Circuit is tested across temperature

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
