ADVANCED LINEAR ALD2332A/ALD2332B/ALD2332 DEVICES, INC. DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER GENERAL DESCRIPTION APPLICATIONS The ALD2332A/ALD2332B/ALD2332 is a monolithic high performance MOSFET driver dual precision voltage comparator built with advanced silicon gate High source impedance voltage comparison EPAD CMOS technology intended for high precision analog applica- circuits tions. The ALD2332A/ALD2332B/ALD2332 offers ultra-low input offset Multiple limit window comparator Power supply voltage monitor voltages and currents at its input pre-amplifier, precision voltage com- Photo-detector sensor circuit parator and high-current output driver integrated on-chip, in one industry High speed LED driver standard pinout 8 Lead PDIP or SOIC package. Primary features include: Oscillators 12 very high typical input impedance of 10 low input bias current of Battery operated instruments 10pA fast response time of 520ns with only 10mV input step signal very Remote signal detection low power dissipation of 175A per comparator single (+5V) or dual Multiple relay drivers (5V) power supply operation and 50mA push-pull output drivers. The input voltage range includes ground, which makes these compara- BENEFITS tors ideal for single supply low level signal detection with high source Simple precision reference voltage setting impedance. The outputs can source and sink current allowing for On-chip input pre-amplifier and output application flexibility. They can be used in either wired-OR connection buffers without pull-up resistor or push-pull configuration. ALD2332A/ALD2332B/ Precision voltage comparison without ALD2332 can also be used in wired-OR connection with other open pre-amplifier drain circuits such as the ALD2331/ALD2303 voltage comparators. Eliminate need for second power supply Eliminate pull-up resistor 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.
