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)
1000.
The
INA333
is
designed
to
use
an
SUPPLY RANGE: +1.8V to +5.5V
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
G
≥ 100), excellent offset voltage drift (0.1
V/°C,
G

LOW QUIESCENT CURRENT: 50A
at G

precision over the extended industrial temperature
range, the INA333 also offers exceptionally low noise
density (50nV/
√Hz) that extends down to dc.
BRIDGE AMPLIFIERS
The INA333 is available in both MSOP-8 and DFN-8
