Description
The INA333 device is a low-power, precision
instrumentation amplifier offering excellent accuracy.
The versatile 3-operational amplifier design, small
size, and low power make it ideal for a wide range of
portable applications.
A single external resistor sets any gain from 1 to
1000. The INA333 is designed to use an industry-standard gain equation: G = 1 + (100 kΩ / RG).
The INA333 device provides very low offset voltage
(25 μV, G ≥ 100), excellent offset voltage drift
(0.1 μV/°C, G ≥ 100), and high common-mode
rejection (100 dB at G ≥ 10). It operates with power
supplies as low as 1.8 V (±0.9 V) and quiescent
current is only 50 μA, making it ideal for battery-operated systems. Using autocalibration techniques
to ensure excellent precision over the extended
industrial temperature range, the INA333 device also
offers exceptionally low noise density (50 nV/√Hz)
that extends down to DC.
The INA333 device is available in both 8-pin VSSOP
and WSON surface-mount packages and is specified
over the TA = –40°C to +125°C temperature range.
