ANALOG DEVICES ADR430/ADR431/ADR433/ADR434/ADR435/ADR439: Ultralow Noise XFET Voltage References with Current Sink Source Capability Data Sheet (Rev J 2011-07-21-)
The ADR430, ADR431, ADR433, ADR434, ADR435, and ADR439 are part of the ADR43x family of XFET voltage references from Analog Devices. These devices feature low noise performance (down to 3.5 pV p-p), high output source and sink current capabilities (+30 mA and -20 mA respectively), and a wide operating temperature range of -40°C to +125°C.
The datasheet provides detailed electrical characteristics, pin configurations for 8-lead MSOP and narrow SOIC packages, and application information. Key features include low temperature coefficients (A Grade: 10 ppm/°C max; B Grade: 3 ppm/°C max), no external capacitor requirement, and the ability to source or sink current directly from the output pin.
