The INA826S device is a low-cost instrumentation amplifier that offers extremely low
power consumption along with shutdown and operates over a very wide single- or dual-supply range. A
single external resistor sets any gain from 1 to 1000. The device offers excellent stability over
temperature, even at G > 1, as a result of the low gain drift of only 35 ppm/°C (max).
The INA826S is optimized to provide excellent common-mode rejection ratio of over 100 dB
(G = 10) over frequencies up to 5 kHz. At 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 INA826S is well-suited for low voltage operation
from a 3-V single supply as well as dual supplies up to ±18 V.
Shutdown pins are provided to reduce supply current below 2 µA. 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.
The INA826S is available in a 10-pin, 3-mm ×
