ORDERING INFORMATION PIN CONFIGURATION BLOCK DIAGRAM GENERAL DESCRIPTION The ALD2301A/ALD2301B/ALD2301/ALD2301C is a monolithic high performance dual 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 300ns; very low power dissipation of 55 µA per comparator; 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. 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/ALD2301/ALD2301C 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. FEATURES • Fanout of 30 LS TTL loads • Low supply current of 110 µA typical • Functional equivalent to LM193 industry standard comparators • Extremely low input bias currents -- 10pA typical • Virtually eliminates source impedance effects • Low operating supply voltage of 3V to 12V • 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 -- 60mA typical • Low supply current spikes APPLICATIONS • High source impedance voltage comparison circuits • Dual limit window comparator • Power supply voltage monitor • Photo-detector sensor circuit • Relay or LED driver • Oscillators • Battery operated instruments • Remote signal detection 1 2 3 4 8 7 6 5 OUT1 -IN 1 +IN 1 GND V+ OUT 2 -IN 2 +IN 2 TOP VIEW DA, PA, SA PACKAGE (1) OUT 1 (7) OUT 2 (4) GND V+ (8) V+ NONINVERTING INPUT +IN 1 (3) INVERTING INPUT NONINVERTING INPUT INVERTING INPUT -IN 1 (2) +IN 2 (5) -IN 2 (6) * Contact factory for industrial temperature range © 1998 Advanced Linear Devices, Inc. 415 Tasman Drive, Sunnyvale, California 94089 -1706 Tel: (408) 747-1155 Fax: (408) 747-1286 http://www.aldinc.com |
