REF1933AIDDCT General Description

The REF1933AIDDCT is a highly versatile product that is essential for applications with only a positive supply voltage, requiring an additional stable voltage in the middle of the analog-to-digital converter (ADC) input range to bias input bipolar signals. With the REF19xx, users can benefit from its capability to provide a reference voltage (VREF) for the ADC and a second highly-accurate voltage (VBIAS) to bias the input bipolar signals. This ensures precision and accuracy in the signal chain, while also reducing board space and overall system cost compared to a discrete solution

Key Features

The REF19 features excellent load regulation.
It is suitable for a wide range of applications, including industrial control systems.
This IC offers reliable performance over its operating temperature range.

Application

Vital in communication technology
For precise measurements
In various electronic systems
