Ultralow Noise XFET® 3.0V Voltage Reference w/Current Sink and Source Capability
The ADR430/ ADR431/ ADR433/ ADR434/ ADR435 series is a family of XFET® voltage references featuring low noise, high accuracy, and low temperature drift performance. Using Analog Devices, Inc., temperature drift curvature correction and extra implanted junction FET (XFET) technology, voltage change vs. temperature nonlinearity in the ADR430/ ADR431/ ADR433/ ADR434/ ADR435 is minimized.
The XFET references operate at lower current (800 μA) and lower supply voltage headroom (2 V) than buried Zener references. Buried Zener references require more than 5 V of headroom for operation. The ADR430/ ADR431/ ADR433/ ADR434/ ADR435 XFET references are low noise solutions for 5 V systems.
The ADR430/ ADR431/ ADR433/ ADR434/ ADR435 family has the capability to source up to 30 mA of output current and sink up to −20 mA. It also comes with a trim terminal to adjust the output voltage over a ±0.5% range without compromising performance.
The ADR430/ ADR431/ ADR433/ ADR434/ ADR435 are available in 8-lead MSOP and 8-lead narrow SOIC packages. All versions are specified over the extended industrial temperature range of −40°C to +125°C.
