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 dy-
namic output impedance (1
Ω typical), excellent initial toler-
ance (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 com-
monly encountered in CMOS data acquisition systems.
As a member of National’s Super-Blockfamily, the LM613
is a space-saving monolithic alternative to a multi-chip solu-
tion, offering a high level of integration without sacrificing
