FEATURES  
DESCRIPTIO  
The LT®1789-1/LT1789-10 are micropower, precision in-  
strumentation amplifiers that are optimized for single supply  
operation from 2.2V to 36V. The quiescent current is 95µA  
max, the inputs common mode to ground and the output  
swings within 110mV of ground. The gain is set with a single  
external resistor for a gain range of 1 to 1000 for the LT1789-  
1 and 10 to 1000 for the LT1789-10.  
Micropower: 95µA Supply Current Max  
Low Input Offset Voltage: 100µV Max  
Low Input Offset Voltage Drift: 0.5µV/°C Max  
Single Gain Set Resistor:  
G = 1 to 1000 (LT1789-1)  
G = 10 to 1000 (LT1789-10)  
Inputs Common Mode to V–  
Wide Supply Range: 2.2V to 36V Total Supply  
CMRR at G = 10: 96dB Min  
The high accuracy of the LT1789-1 (40ppm maximum  
nonlinearity and 0.25% max gain error) is unmatched by  
othermicropowerinstrumentationamplifiers.TheLT1789-10  
maximizesboththeinputcommonmoderangeanddynamic  
output range when an amplification of 10 or greater is  
required, allowing precise signal processing where other  
instrumentation amplifiers fail to operate. The LT1789-1/  
LT1789-10 are laser trimmed for very low input offset  
voltage, low input offset voltage drift, high CMRR and high  
PSRR. The output can handle capacitive loads up to 400pF  
(LT1789-1), 1000pF (LT1789-10) in any gain configuration  
whiletheinputsareESDprotectedupto10kV(humanbody).  
Gain Error: G = 10, 0.25% Max  
Gain Nonlinearity: G = 10, 40ppm Max  
Input Bias Current: 40nA Max  
PSRR at G = 10: 100dB Min  
1kHz Voltage Noise: 48nV/Hz  
0.1Hz to 10Hz Noise: 1.5µVP-P

The LT1789-1/LT1789-10 are offered in the 8-pin SO pack-  
age, requiring significantly less PC board area than discrete  
multi op amp and resistor designs.
