Key Featrues
Dual Output Voltage Reference (VREF and VBIAS): The REF20xx provides two highly accurate output voltages, VREF and VBIAS (VREF/2), which are ideal for single-supply systems. This dual-output capability simplifies biasing of bipolar signals in analog-to-digital converters (ADCs), improving signal chain precision and reducing the need for additional components, thereby saving board space and cost.
Exceptional Temperature Drift Performance (8 ppm/°C): With a maximum temperature drift of 8 ppm/°C across a wide temperature range (-40°C to 125°C), the REF20xx ensures stable and accurate voltage references even in harsh environments. This feature enhances the reliability and precision of industrial and battery-operated applications.
Low Dropout Voltage (10 mV): The REF20xx operates with an extremely low dropout voltage of just 10 mV, enabling it to function efficiently from very low input voltages. This makes it particularly suitable for battery-powered systems, where maximizing energy efficiency is critical.
Low Quiescent Current (360 µA): The device consumes only 360 µA of quiescent current, making it highly power-efficient. This low power consumption is beneficial for portable and energy-sensitive applications, extending battery life and reducing overall system power requirements.
High Output Current Capability (±20 mA): The REF20xx can source and sink up to 20 mA of current, providing robust support for driving loads in precision applications. This high output current capability ensures stable performance even under varying load conditions, making it suitable for a wide range of industrial and measurement systems.
