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 de-
signed to lower cost and board space requirements in trans-
ducer, 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 refer-
ence consists of a reliable band-gap design that maintains
low dynamic output impedance (1
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
family, the LM611
is a space-saving monolithic alternative to a multi-chip solu-
tion, offering a high level of integration without sacrificing
performance.
