DESCRIPTION
The LM611 consists of a single-supply op-amp and a
programmable 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 reference 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
reference is very stable even when driving large
capacitive loads, as are commonly encountered in
CMOS data acquisition systems.
As a member of TI's Super-Block family, the LM611
is a space-saving monolithic alternative to a multi-
chip solution, offering a high level of integration
without sacrificing performance.
