LOW OFFSET VOLTAGE: 25V (max), G ≥ 100
The INA333 is a low-power, precision instrumentation
amplifier offering excellent accuracy. The versatile
LOW DRIFT: 0.1V/°C, G ≥ 100
3-op amp design, small size, and low power make it
LOW NOISE: 50nV/√Hz, G ≥ 100
ideal for a wide range of portable applications.
HIGH CMRR: 100dB (min), G ≥ 10
A single external resistor sets any gain from 1 to
LOW INPUT BIAS CURRENT: 200pA (max)

The
INA333
is
designed
to

industry-standard gain equation: G = 1 + (100k
/RG).
INPUT VOLTAGE: (V–) +0.1V to (V+) –0.1V
The INA333 provides very low offset voltage (25
V,
OUTPUT RANGE: (V–) +0.05V to (V+) –0.05V
