ADR431ARMZ 参考电压 IC

ADR431ARMZ

参考电压 2.5V w/Crnt Sink & Srce Capability

Ultralow Noise XFET Voltage References  with Current Sink and Source Capability

GENERAL DESCRIPTION ADR431ARMZ

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.
