FEATURES
DESCRIPTION
The LM614 consists of four op-amps and
a
23
Op Amp
programmable voltage reference in a 16-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 four wide
output swing op-amps makes the LM614 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), initial tolerance (2.0%), and
the ability to be programmed from 1.2V to 5.0V 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.
Wide Operating Current Range: 17μA to
