BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4742
SINGLE SUPPLY VOLTAGE, HIGH SPEED,
WIDE BAND, DUAL OPERATIONAL AMPLIFIERS
The µPC4742 is dual high speed, wide band operational amplifier designed for single supply operation from
+3 V to +32 V with low supply current drain. By using high speed PNP transistors for input and output circuits,
the excellent AC performance is achieved without degrading capacitive load drive capability.
With no crossover distortion and wide output voltage range characteristics, the µPC4742 is optimum choice for
single supply AC amplifier, and active filters.
FEATURES
• High slew rate: 7 V/µs TYP. (V+ = +5 V, V– = GND)
• Wide gain band width product: 3.5 MHz TYP. (V+ = +5 V, V– = GND)
• Wide supply voltage range: +3 V to +32 V
• Wide output voltage swing
• Common mode input voltage range includes V–
• Internal frequency compensation
• Output short circuit protection
