Advanced Linear Devices ALD4301A
The ALD4301A/ALD4301 is a monolithic high performance quad voltage comparator built with advanced silicon gate CMOS technology. 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. The input voltage range includes ground, making this comparator ideal for low level signal detection with high source impedance.| Part No. | ALD4301A |

GENERAL DESCRIPTION
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 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 circuits requiring very low input currents and low standby power, yet retaining high output current capability.FEATURES
