Description

The INA317 is a low-power, precision instrumentation amplifier offering excellentaccuracy. The versatile 3-operational amplifier design, small size and low power make the INA317usable in a wide range of portable applications.

A single external resistor sets any gain from 1 to 1000, as defined by theindustry-standard gain equation: G = 1 (100 kΩ /R_G).

The instrumentation amplifier provides low offset voltage (75 µV, G ≥ 100), excellentoffset voltage drift
(0.3 µV/°C, G ≥ 100) and high common-mode rejection (100 dB at G ≥ 10). The INA317 operateswith power supplies as low as 1.8 V (±0.9 V) and a quiescent current of 50 µA, making the deviceusable in battery-operated systems. Using autocalibration techniques to ensure precision over theextended industrial temperature range, the INA317 device offers low noise density (50nV/√Hz) that extends down to DC.

The INA317 is available in an 8-pin VSSOP surface-mount package and is specified over theT_A = –40°C to 125°C temperature range.
