ALD4302A/ALD4302  
QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER  
GENERAL DESCRIPTION  
APPLICATIONS  
The ALD4302 is a monolithic high performance quad voltage comparator  
built with advanced silicon gate CMOS technology. It features very high  
typical input impedance of 10 Ω; low input bias current of 10pA; fast  
response time of 120ns; very low power dissipation of 150µA per compara-  
tor; and single +5V or dual ±5V power supply operation.  
• MOSFET driver  
• High source impedance voltage  
comparison circuits

• Multiple limit window comparator  
• Power supply voltage monitor  
• Photo-detector sensor circuit  
• High speed LED driver  
• Oscillators  
• Battery operated instruments  
• Remote signal detection  
• Multiple relay drivers  
The input voltage range includes ground, making this comparator ideal for  
single supply low level signal detection with high source impedance. The  
outputscansourceandsinkcurrent,allowingapplicationflexibility,andcan  
be used in either wired-OR connection without pull up resistor or push-pull  
configuration. The ALD4302 can be used in wired-OR connection with  
other open drain circuits such as the ALD2301 and ALD2303 voltage  
comparators.  
PIN CONFIGURATION  
The ALD4302 is ideal for a great variety of precision voltage comparator  
applications, especially low level signal detection circuits requiring low  
standby power, yet retaining high output current capability.
