INA333AIDGKR Micro-Power Zerø-Drift, Rail-to-Rail Out Instrumentation Amplifier VSSOP8 spot stock

Product Descriptions

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 auto calibration 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 T_A = –40°C to +125°C temperature range.​
