LM613
Dual Operational Amplifiers, Dual Comparators, and
Adjustable Reference
General Description
The LM613 consists of dual op-amps, dual comparators, and
a programmable voltage reference in a 16-pin package. The
op-amps out-performs most single-supply op-amps by pro-
viding higher speed and bandwidth along with low supply
current. This device was specifically designed to lower cost
and board space requirements in transducer, test, measure-
ment, and data acquisition systems.
Combining a stable voltage reference with wide output swing
op-amps makes the LM613 ideal for single supply transduc-
ers, 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 tol-
erance (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 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.
