LM611
Operational Amplifier and Adjustable Reference
General Description
The LM611 consists of a single-supply op-amp and a pro-
grammable voltage reference in one space saving 8-pin
package. The op-amp out-performs most single-supply op-
amps by providing higher speed and bandwidth along with
low supply current. This device was specifically designed to
lower cost and board space requirements in transducer, test,
measurement and data acquisition systems.
Combining a stable voltage reference with a wide output
swing op-amp makes the LM611 ideal for single supply
transducers, signal conditioning and bridge driving where
large common-mode signals are common. The voltage ref-
erence consists of a reliable band-gap design that maintains
low dynamic output impedance (1Ω typical), excellent initial
tolerance (0.6%), and the ability to be programmed from
1.2V to 6.3V via two external resistors. The voltage refer-
ence is very stable even when driving large capacitive loads,
as are commonly encountered in CMOS data acquisition
systems.
As a member of National’s Super-Block
is a space-saving monolithic alternative to a multi-chip solu-
tion, offering a high level of integration without sacrificing
performance.
