REF2033AIDDCT Describe
Applications with only a positive supply voltage typically require an additional regulated voltage in the middle of the analog-to-digital converter (ADC) input range to bias the input bipolar signal. The REF20xx provides a reference voltage (VREF) that can be used by the ADC and a high precision voltage (VBIAS) that can be used to bias the input bipolar signal.
The REF20xx features excellent temperature drift (8 ppm/°C max) and initial accuracy (0.05%) on the VREF and VBIAS outputs while maintaining a quiescent operating current of less than 430µA. Additionally, the VREF and VBIAS outputs track each other with an accuracy of 6 ppm/°C (max) over the temperature range of –40°C to 85°C. All of these features increase the accuracy of the signal chain, save board space, and reduce system cost compared to discrete solutions. An ultra-low dropout voltage of only 10mV allows the device to operate from very low input voltages, which is ideal for battery-powered systems.
The VREF and VBIAS voltages have equally good specifications and are equally capable of sinking and sourcing current. These devices feature excellent long-term stability and low noise levels, making them ideal for high-precision industrial applications.
