SNVS053E –JUNE 2000–REVISED APRIL 2013  
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.  
2
•
•
•
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.
