FEATURES
DESCRIPTION
The INA826 is a low-cost instrumentation amplifier

• Input Common-Mode Range: Includes V–
that offers extremely low power consumption and
• Common-Mode Rejection:
operates over a very wide single or dual supply
– 104 dB, min (G = 10)
range. A single external resistor sets any gain from 1
to 1000. It offers excellent stability over temperature,
– 100 dB, min at 5 kHz (G = 10)
even at G > 1, as a result of the low gain drift of only

35 ppm/°C (max).
• Low Offset Voltage: 150 µV, max
The INA826 is optimized to provide excellent
• Gain Drift: 1 ppm/°C (G = 1), 35 ppm/°C (G > 1)
common-mode rejection ratio of over 100 dB (G = 10)
• Noise: 18 nV/√Hz, G ≥ 100
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
• Inputs Protected up to ±40 V
all the way up to 1 V of the positive supply. Using a
• Rail-to-Rail Output
rail-to-rail output, the INA826 is well-suited for low
voltage operation from a 2.7 V single supply as well
• Supply Current: 200 µA
as dual supplies up to ±18 V.
• Supply Range:
Additional circuitry protects the inputs against

overvoltage of up to ±40 V beyond the power
– Dual Supply: ±1.35 V to ±18 V
supplies by limiting the input currents to less than
