LM614 Quad Operational Amplifier and Adjustable Reference
February 1995
LM614 Quad Operational Amplifier
and Adjustable Reference
General Description
The LM614 consists of four op-amps and a programmable
voltage reference in a 16-pin package The op-amp out-per-
forms 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 ref-
erence consists of a reliable band-gap design that maintains
low dynamic output impedance (1X 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 acquisi-
tion systems
As a member of National鈥檚 new Super-Block
TM
family the
LM614 is a space-saving monolithic alternative to a multi-
chip solution offering a high level of integration without sac-
rificing performance
