ADR435BRMZ Ultralow Noise XFET Voltage References with Current Sink and Source Capability MSOP8 spot stock

Product Descriptions

The ADR430/ADR431/ADR433/ADR434/ADR435¹ 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.
