ADVANCED LINEAR DEVICES, INC. ALD2301A/ALD2301B ALD2301C/ALD2301 DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH OPEN DRAIN DRIVER GENERAL DESCRIPTION FEATURES The ALD2301A/ALD2301B/ALD2301C/ALD2301 is a monolithic high performance dual 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; and single (+5V) or dual (±5V) power supply operation. • Fanout of 30LS TTL loads • Low supply current of 110µA typical • Functional equivalent to LM193 industry standard comparators • Extremely low input bias currents -- typically 10pA • Virtually eliminates source impedance effects • Low operating supply voltage of 3V to 10V • Single (+5V) and dual supply (±5V) operation • High speed for both large signal and low level signals -- 300ns typical for TTL inputs • CMOS, NMOS and TTL compatible • Wired-OR open drain outputs • High output sinking current -- typically 60mA • Low supply current spikes 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, such as wired-OR connection. The outputs can be connected to a higher external voltage than V +. The ALD2301A/ALD2301B/ALD2301C/ALD2301 is ideal for a great variety of voltage comparator applications, especially low level signal detection circuits requiring low standby power, yet retaining high output current capability as needed.
