ALD4301A/ALD4301  
QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH OPEN DRAIN DRIVER  
APPLICATIONS  
GENERAL DESCRIPTION  
• High source impedance voltage  
comparison circuits  
• Dual/Quad limit window comparator  
• Power supply voltage monitor  
• Photo-detector sensor circuit  
• Relay or LED driver  
The ALD4301A/ALD4301 is a monolithic high performance quad  
voltage comparator built with advanced silicon gate CMOS technol-  
ogy. It features very high typical input impedance of 1012Ω; low input  
bias current of 10pA; fast response time of 300ns; very low power  
dissipation of 55µA per comparator; high output drive and single  
(+5V) or dual (±5V) power supply operation.  
• Oscillators  
• Battery operated instruments  
• Remote signal detection  
The input voltage range includes ground, making this comparator  
ideal for low level signal detection with high source impedance. The  
outputs are open-drain configuration, allowing maximum application  
flexibility. The outputs can be connected to a higher external voltage  
+
than V and used in a wired-OR connection with other open drain  
PIN CONFIGURATION  
circuits such as the ALD2301 and ALD2303. They can also be used  
with push-pull output types, such as the ALD2302 and ALD4302  
voltage comparators, simultaneously with open drain comparators  
using a common V+. The ALD4301A/ALD4301 is ideal for a great  
variety of voltage comparator applications, especially detection cir-  
cuits requiring very low input currents and low standby power, yet  
retaining high output current capability.
