ADR445ARMZ
参考电压 LDO 5.0V w/ Crnt Sink & Srce
Ultralow Noise, LDO XFET Voltage References with Current Sink and Source
GENERAL DESCRIPTION ADR445ARMZ
The ADR440/ADR441/ADR443/ADR444/ADR4451 series is a family of XFET® voltage references featuring ultralow 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 ADR440/ADR441/ ADR443/ADR444/ADR445 is greatly minimized.
FEATURES ADR445ARMZ
Ultralow noise (0.1 Hz to 10 Hz)
ADR440: 1 μV p-p
ADR441: 1.2 μV p-p
ADR443: 1.4 μV p-p
ADR444: 1.8 μV p-p
ADR445: 2.25 μV p-p
Superb temperature coefficient
A grade: 10 ppm/°C
B grade: 3 ppm/°C
Low dropout operation (supply voltage headroom): 500 mV
Input range: (VOUT + 500 mV) to 18 V
High output source and sink current
+10 mA and −5 mA, respectively
Wide temperature range: −40°C to +125°C
