LT1920  
Single Resistor Gain  
Programmable, Precision  
Instrumentation Amplifier

DESCRIPTIO  
FEATURES  
The LT®1920 is a low power, precision instrumentation  
amplifier that requires only one external resistor to set gains  
of 1 to 10,000. The low voltage noise of 7.5nV/Hz (at 1kHz)  
isnotcompromisedbylowpowerdissipation(0.9mAtypical  
for ±2.3V to ±15V supplies).  
Single Gain Set Resistor: G = 1 to 10,000  
Gain Error: G = 10, 0.3% Max  
Gain Nonlinearity: G = 10, 30ppm Max  
Input Offset Voltage: G = 10, 225µV Max  
Input Offset Voltage Drift: 1µV/°C Max  
Input Bias Current: 2nA Max  
PSRR at G = 1: 80dB Min  
CMRR at G = 1: 75dB Min  
Supply Current: 1.3mA Max  
Wide Supply Range: ±2.3V to ±18V  
1kHz Voltage Noise: 7.5nV/Hz  
0.1Hz to 10Hz Noise: 0.28µVP-P  
Available in 8-Pin PDIP and SO Packages  
Meets IEC 1000-4-2 Level 4 ESD Tests with  
Two External 5k Resistors  
The high accuracy of 30ppm maximum nonlinearity and  
0.3% max gain error (G = 10) is not degraded even for load  
resistors as low as 2k (previous monolithic instrumentation  
amps used 10k for their nonlinearity specifications). The  
LT1920 is laser trimmed for very low input offset voltage  
(125µV max), drift (1µV/°C), high CMRR (75dB, G = 1) and  
PSRR (80dB, G = 1). Low input bias currents of 2nA max are  
achieved with the use of superbeta processing. The output  
canhandlecapacitiveloadsupto1000pFinanygainconfigu-  
ration while the inputs are ESD protected up to 13kV (human  
body). The LT1920 with two external 5k resistors passes the  
IEC 1000-4-2 level 4 specification.  
U
APPLICATIO S  
The LT1920, offered in 8-pin PDIP and SO packages, is a pin  
for pin and spec for spec improved replacement for the  
AD620. The LT1920 is the most cost effective solution for  
precision instrumentation amplifier applications. For even  
better guaranteed performance, see the LT1167.
