3 Description
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 commonmode
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 ×
3-mm VSON surface-mount package. The INA826S
is specified over the –40°C to +125°C temperature
range.
