LM4140 High Precision Low Noise Low Dropout Voltage Reference

Check for Samples: LM4140

FEATURES

DESCRIPTION

The LM4140 series of precision references are

designed to combine high accuracy, low drift and

noise with low power dissipation in a small package.

•

High Initial Accuracy: 0.1%

Ultra Low Noise

Low Temperature Coefficient: 3 ppm/°C (A

grade)

The LM4140 is the industry's first reference with

output voltage options lower than the bandgap

voltage.

•

Low Voltage Operation: 1.8V

Low Dropout Voltage: 20 mV (typ) @ 1mA

Supply Current: 230 μA (typ), ≤ 1 μA Disable

Mode

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.

•

Enable Pin

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 economically with most methods utilized by

other bandgap references.

•

Custom Voltages from 0.5V to 4.5V

Temperature Range (0°C to 70°C)

APPLICATIONS SUMMARY

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.

•

Portable, Battery Powered Equipment

Instrumentation and Test Equipment

Automotive

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

with 0.1% initial accuracy and 3, 6 and 10 ppm/°C

temperature coefficients. For even lower Tempco,

contact Texas Instruments.

Industrial Process Control

Data Acquisition Systems

Medical Equipment

Precision Scales

The device performance is specified over the

temperature range (0°C to +70°C) and is available in

compact 8-pin package.

Servo Systems

Battery Charging

For other output voltage options from 0.5V to

4.5V, contact Texas Instruments.
