General DescriptionThe LM611 consistsofa single-supply op-ampanda pro-
grammable voltage referencein one space saving 8-pin
package. The op-amp out-performs most single-supply
op-ampsby providing higher speed and bandwidth along
withlow supply current. This device was specificallyde-
signedto lower costand board space requirementsin trans-
ducer, test, measurementand data acquisition systems.
Combininga stable voltage reference witha wide output
swing op-amp makesthe LM611 idealfor single supply
transducers, signal conditioning and bridge driving where
large common-mode signalsare common.The voltagerefer-
ence consistsofa reliable band-gap designthat maintains
low dynamic output impedance(1Ω typical), excellent initial
tolerance (0.6%), andthe abilitytobe programmed from
1.2Vto 6.3Vviatwo external resistors. The voltage refer-
enceis very stable evenwhen drivinglarge capacitiveloads,are commonly encounteredin CMOS data acquisition
systems.a memberof National’s Super-Block™ family,the LM611a space-saving monolithic alternativetoa multi-chip solu-
tion, offeringa high levelof integration without sacrificing
performance.
