LM611

Operational Amplifier and Adjustable Reference

General Description

The LM611 consists of a single-supply op-amp and a pro-

grammable voltage reference in one space saving 8-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 de-

signed to lower cost and board space requirements in trans-

ducer, test, measurement and data acquisition systems.

Combining a stable voltage reference with a wide output

swing op-amp makes the LM611 ideal for single supply

transducers, signal conditioning and bridge driving where

large common-mode signals are common. The voltage refer-

ence consists of a reliable band-gap design that maintains

low dynamic output impedance (1

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 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.
