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.
FEATURES ADR431ARMZ
