LM4140

High Precision Low Noise Low Dropout Voltage

Reference

General Description

Features

n High initial accuracy: 0.1%

n Ultra low noise

The LM4140 series of precision references are designed to

combine high accuracy, low drift and noise with low power

dissipation in a small package.

n Low Temperature Coefficient: 3 ppm/˚C (A grade)

n Low voltage operation: 1.8V

n SO-8 package

The LM4140 is the industry’s first reference with output

voltage options lower than the bandgap voltage.

The key to the advance performance of the LM4140 is the

use of EEPROM registers and CMOS DACs for temperature

coefficient curvature correction and trimming of the output

voltage accuracy of the device during the final production

testing.

n Low dropout voltage: 20 mV (typ) 1mA

n Supply Current: 230 µA (typ), ≤ 1 µA disable mode

n Enable pin

n Output voltage options: 1.024V, 1.250V, 2.048V, 2.500V,

and 4.096V

The major advantage of this method is the much higher

resolution available with DACs than is available economi-

cally with most methods utilized by other bandgap refer-

ences.

n Custom voltages from 0.5V to 4.5V

n Temperature range (0˚C to 70˚C)

Applications Summary

n Portable, battery powered equipment

n Instrumentation and test equipment

n Automotive

n Industrial process control

n Data acquisition systems

n Medical equipment

The low input and dropout voltage, low supply current and

output drive capability of the LM4140 makes this product an

ideal choice for battery powered and portable applications.

The LM4140 is available in three grades (A, B, C) with 0.1%

initial accuracy and 3, 6 and 10 ppm/˚C temperature coeffi-

cients. For even lower Tempco, contact National Semicon-

ductor.

n Precision scales

n Servo systems

n Battery charging

The device performance is specified over the temperature

range (0˚C to +70˚C) and is available in compact 8-pin SO

package.

For other output voltage options from 0.5V to 4.5V, con-

tact National Semiconductor.
