ADVANCED LINEAR DEVICES, INC. ALD2332A/ALD2332B/ALD2332 DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER GENERAL DESCRIPTION APPLICATIONS The ALD2332A/ALD2332B/ALD2332 is a monolithic high performance dual precision voltage comparator built with advanced silicon gate EPAD® CMOS technology intended for high precision analog applications. The ALD2332A/ALD2332B/ALD2332 offers ultra-low input offset voltages and currents at its input pre-amplifier, precision voltage comparator and high-current output driver integrated on-chip, in one industry standard pinout 8 Lead PDIP or SOIC package. Primary features include: very high typical input impedance of 1012Ω; low input bias current of 10pA; fast response time of 520ns with only 10mV input step signal; very low power dissipation of 175µA per comparator; single (+5V) or dual (±5V) power supply operation; and 50mA push-pull output drivers. • MOSFET driver • High source impedance voltage comparison circuits • Multiple limit window comparator • Power supply voltage monitor • Photo-detector sensor circuit • High speed LED driver • Oscillators • Battery operated instruments • Remote signal detection • Multiple relay drivers The input voltage range includes ground, which makes these comparators ideal for single supply low level signal detection with high source impedance. The outputs can source and sink current allowing for application flexibility. They can be used in either wired-OR connection without pull-up resistor or push-pull configuration. ALD2332A/ALD2332B/ ALD2332 can also be used in wired-OR connection with other open drain circuits such as the ALD2331/ALD2303 voltage comparators. BENEFITS The ALD2332A/ALD2332B/ALD2332 voltage comparators are ideal for a great variety of precision analog voltage comparator applications, especially in low level signal detection circuits which require low standby power and high output current. • Simple precision reference voltage setting • On-chip input pre-amplifier and output buffers • Precision voltage comparison without pre-amplifier • Eliminate need for second power supply • Eliminate pull-up resistor PIN CONFIGURATION FEATURES • • • • • • • • • • • • • • Guaranteed to drive 200Ω loads Fanout of 30LS TTL loads Low supply current of 175µA each comparator Pinout of LM193 type industry standard voltage comparators Extremely low input bias currents -- typically 10pA Virtually eliminates source impedance effects Low operating supply voltage of 4V to 10V Single (+5V) and dual supply (±5V) operation High speed for both large and small signals -180ns for TTL inputs and 400ns for 20mV overdrive CMOS, NMOS and TTL compatible Push-pull outputs-current sourcing/ sinking High output sinking current -- typically 50mA Low supply current spikes High gain -- 100V/mV OUT 1 1 8 V+ -IN 1 2 7 OUT 2 +IN 1 3 6 -IN 2 GND 4 5 +IN 2 SAL, PAL PACKAGES BLOCK DIAGRAM (8) V+ ORDERING INFORMATION (“L” suffix for lead free version) Operating Temperature Range * 0°C to +70°C 0°C to +70°C 8-Pin Small Outline Package (SOIC) ALD2332ASAL ALD2332BSAL ALD2332SAL 8-PinPlastic Dip Package ALD2332APAL ALD2332BPAL ALD2332PAL INVERTING INPUT -IN 1 (2) (1) OUT 1 NONINVERTING INPUT +IN 1 (3) V+ INVERTING INPUT -IN 2 (6) (7) OUT 2 NONINVERTING INPUT +IN 2 (5) (4) GND * Contact factory for leaded (non-RoHS) or high temperature versions.

TIME DELAY GENERATOR V+ RF1 V1 V+ VREF VIN + RT RF2 V2 + + CT RF3 V3 + RF4 Design & Operating Notes: 1. As each output sources up to 10mA in the output high state, the output stage of a wired - OR low output circuit must be able to sink this current and still provide desired output voltage levels. For TTL output levels, this consideration limits the number to a maximum of three ALD2302 outputs wired-OR together. 2. In order to minimize stray oscillation, all unused inputs must be tied to ground. 3. The input bias and offset currents are essentially input protection diode reverse bias leakage currents, and are typically less than 1 pA at room temperature. The currents are a function of ambient temperature, and would have to be considered in applications where very high source impedance or high accuracy are involved. 4. The high output sinking current of 60mA for each output offers flexibility in many applications, as a separate buffer or driver would not be necessary to drive the intended load. However, as the circuit normally operates close to ambient temperature due to its very low power consumption, thermal effects caused by large output current transients must be considered in certain applications.
