LS404CDT STMicroelectronics

LS404 HIGH PERFORMANCE QUAD OPERATIONAL AMPLIFIER SINGLE OR SPLIT SUPPLY OPERATION LOW POWER CONSUMPTION SHORT CIRCUIT PROTECTION LOW DISTORTION, LOW NOISE HIGH GAIN-BANDWIDTH PRODUCT N HIGH CHANNEL SEPARATION DIP14 (Plastic Package) DESCRIPTION The LS404 is a high performance quad operation- al amplifier with frequency and phase compensa- tion built into the chip. The internal phase compen- sation allows stable operation as voltage follower in spite of its high Gain-Bandwidth Product. D The circuit presents very stable electrical charac- SO14 (Plastic Micropackage) teristics over the entire supply voltage range, and is particularly intended for professional and tele- com applications (active filter, etc). PIN CONNECTIONS (top view) 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.
