16-Pin Wide

Body SOIC

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-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 ref-

erence consists of a reliable band-gap design that maintains

low dynamic output impedance (1

(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.

As a member of National’s new Super-Block

LM614 is a space-saving monolithic alternative to a multichip

solution, offering a high level of integration without sacrificing

performance.
