ADVANCED LINEAR ALD4302A/ALD4302 DEVICES, INC. QUAD PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER GENERAL DESCRIPTION APPLICATIONS The ALD4302A/ALD4302 is a monolithic high performance quad voltage MOSFET driver comparator built with advanced silicon gate CMOS technology. It features High source impedance voltage 12 very high typical input impedance of 10 low input bias current of 10pA comparison circuits fast response time of 120ns very low power dissipation of 150A per Multiple limit window comparator comparator and single (+5V) or dual (5V) power supply operation. Power supply voltage monitor Photo-detector sensor circuit The input voltage range includes ground, making this comparator ideal for High speed LED driver single supply low level signal detection with high source impedance. The Oscillators outputs can source and sink current, allowing application flexibility, and Battery operated instruments can be used in either wired-OR connection without pull up resistor or push- Remote signal detection pull configuration. The ALD4302A/ALD4302 can be used in wired-OR Multiple relay drivers connections with other open drain circuits such as the ALD2301 and ALD2303 voltage comparators. PIN CONFIGURATION The ALD4302A/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. 02 1 14 03 2 01 13 04 + 3 12 FEATURES V GND Guaranteed to drive 200 loads -IN 4 11 +IN 1 4 Fanout of 30LS TTL loads Low supply current of 150A each comparator +IN 5 10 -IN 1 4 Extremely low input bias currents -- typically 10pA -IN 6 9 +IN Virtually eliminates source impedance effects 2 3 Low operating supply voltage of 4V to 10V +IN 7 8 -IN 2 3 Single (+5V) and dual supply (5V) operation High speed for both large and small signals - SBL, PBL, DB PACKAGES 120ns for TTL inputs and 400ns for 5mV overdrive CMOS, NMOS and TTL compatible Push-pull outputs BLOCK DIAGRAM High output sinking current -- typically 60mA Low supply current spikes + V (3) High gain -- 100V/mV INVERTING INPUT - - IN (4) 1 (2) OUT 1 NONINVERTING INPUT + ORDERING INFORMATION (L suffix for lead free version) +IN (5) 1 Operating Temperature Range * INVERTING INPUT - - IN (6) 2 0C to +70C0C to +70C -55C to +125C (1) OUT 2 NONINVERTING INPUT + + IN (7) 2 14-Pin 14-Pin 14-Pin Small Outline Plastic Dip CERDIP INVERTING INPUT - Package (SOIC) Package Package - IN (8) 3 (14) OUT 3 NONINVERTING INPUT + + IN (9) 3 ALD4302ASBL ALD4302APBL ALD4302ADB - INVERTING INPUT - IN (10) ALD4302SBL ALD4302PBL ALD4302DB 4 (13) OUT 4 NONINVERTING INPUT + + IN (11) 4 * Contact factory for leaded (non-RoHS) or high temperature versions.
