FEATURES  
DESCRIPTION  
The LT®1789-1/LT1789-10 are micropower, precision  
instrumentation amplifiers that are optimized for single  
n
Micropower: 95μA Supply Current Max  
n
Low Input Offset Voltage: 100μV Max  
n
Low Input Offset Voltage Drift: 0.5μV/°C Max  
Single Gain Set Resistor:  
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.

Wide Supply Range: 2.2V to 36V Total Supply  
CMRR at G = 10: 96dB Min  
The high accuracy of the LT1789-1 (40ppm maximum non-  
linearity and 0.25% max gain error) is unmatched by other  
micropower instrumentation amplifiers. The LT1789-10  
maximizesboththeinputcommonmoderangeanddynamic  
outputrangewhenanamplificationof10orgreaterisrequired,  
allowingprecisesignalprocessingwhereotherinstrumenta-  
tion 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  
canhandlecapacitiveloadsupto400pF(LT1789-1), 1000pF  
(LT1789-10) in any gain configuration while the inputs are  
ESD protected up to 10kV (human body).  
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: 1.5μV

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