FEATURES  
DESCRIPTION  
The INA826 is a low-cost instrumentation amplifier  
234  
Input Common-Mode Range: Includes V–  
Common-Mode Rejection:  
that offers extremely low power consumption and  
operates over a very wide single or dual supply  
range. A single external resistor sets any gain from 1  
to 1000. It offers excellent stability over temperature,  
even at G > 1, as a result of the low gain drift of only  
35 ppm/°C (max).  
104 dB, min (G = 10)  
100 dB, min at 5 kHz (G = 10)  
Power-Supply Rejection: 100 dB, min (G = 1)  
Low Offset Voltage: 150 µV, max  
Gain Drift: 1 ppm/°C (G = 1), 35 ppm/°C (G > 1)  
Noise: 18 nV/Hz, G 100  
The INA826 is optimized to provide excellent  
common-mode rejection ratio of over 100 dB (G = 10)  
over frequencies up to 5 kHz. In G = 1, the common-  
mode rejection ratio exceeds 84 dB across the full  
input common-mode range from the negative supply  
all the way up to 1 V of the positive supply. Using a  
rail-to-rail output, the INA826 is well-suited for low  
voltage operation from a 2.7 V single supply as well  
as dual supplies up to ±18 V.  
Bandwidth: 1 MHz (G = 1), 60 kHz (G = 100)  
Inputs Protected up to ±40 V  
Rail-to-Rail Output  
Supply Current: 200 µA  
Supply Range:  
Additional circuitry protects the inputs against  
overvoltage of up to ±40 V beyond the power  
supplies by limiting the input currents to less than  
8 mA.  
Single Supply: +2.7 V to +36 V  
Dual Supply: ±1.35 V to ±18 V  
Specified Temperature Range:  
–40°C to +125°C  
The INA826 is available in SO-8, MSOP-8, and tiny  
3-mm × 3-mm DFN-8 surface-mount packages. All  
versions are specified for the –40°C to +125°C  
temperature range.  
Packages: MSOP-8, SO-8 and DFN-8
