LS404 HIGH PERFORMANCE QUAD OPERATIONAL AMPLIFIERS .. .. .. SINGLE OR SPLIT SUPPLY OPERATION LOW POWER CONSUMPTION SHORT CIRCUIT PROTECTION LOW DISTORTION, LOW NOISE HIGH GAIN-BANDWIDTH PRODUCT HIGH CHANNEL SEPARATION DESCRIPTION The LS404 is a high performance quad operational amplifier with frequency and phase compensation built intothe chip. The internal phasecompensation allows stable operation as voltage follower in spite of its high Gain-Bandwidth Product. The circuit presents very stable electrical characteristics over the entire supply voltage range, and it particularly intended for professional and telecom applications (active filters, etc). The patented input stage circuit allows small input signal swings below the negative supply voltage and prevents phase inversion when the inputs are over drivers.
