Advanced Linear Devices ALD4302A
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 1012 Ω; low input bias current of 10pA; fast response time of 120ns; very low power dissipation of 150 µA per comparator; and single +5V or dual ±5V power supply operation. The input voltage range includes ground, making this comparator ideal for single supply low level signal detection with high source impedance.| Part No. | ALD4302A |

GENERAL DESCRIPTION
The outputs can source and sink current, allowing application flexibility, and can 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. 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.FEATURES
