• LOW OFFSET VOLTAGE: 25 µ V (max), G ≥ 100
The INA333 is a low-power, precision instrumentation
amplifier offering excellent accuracy. The versatile
• LOW DRIFT: 0.1 µ V/ ° 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 Ω /R
G
).
• INPUT VOLTAGE: (V – ) +0.1V to (V+) – 0.1V
The INA333 provides very low offset voltage (25 µ V,
• OUTPUT RANGE: (V – ) +0.05V to (V+) – 0.05V
G ≥ 100), excellent offset voltage drift (0.1 µ V/ ° C,
G ≥ 100), and high common-mode rejection (100dB
• LOW QUIESCENT CURRENT: 50 µ A
at G ≥ 10). It operates with power supplies as low as
• OPERATING TEMPERATURE: – 40 ° C to +125 ° C
1.8V ( ± 0.9V), and quiescent current is only

precision over the extended industrial temperature
range, the INA333 also offers exceptionally low noise
density (50nV/ √ Hz) that extends down to dc.
