TECHNICAL SPECIFICATION SL4558 Dual Operational Amplifiers The SL4558 is dual general purpose operational amplifiers. The high common-mode input voltage range and the absence of latch-up make these amplifiers ideal for voltage follower application. The devices are short circuit protected and the internal frequency Compensation ensures stability without external components. • • • • • • • • Short Circuit Protection Wide common-mode and differential ranges No frequency compensation required Low power consumption No latch-up 3 MHz unity gain bandwidth guaranteed Gain and phase match between amplifiers Possible to exchange the position of Pin9 for Pin1 because of Pin Connection being symmetric(SL4558S only) ORDERING INFORMATION SL4558N Plastic SL4558D SOIC SL4558S SIP-8 TA = -20° to 70° C for all packages.
