Zero drift 36 V in-amp

25 November 2015 Analogue, Mixed Signal, LSI

Texas Instruments introduced the industry’s first zero-drift, 36 V instrumentation amplifier. The INA188 delivers high accuracy for precise DC and low-frequency measurements in applications such as test and measurement, medical and industrial process control equipment. It also eliminates the 1/f corner and features best-in-class offset drift to enable accurate measurement over the full extended industrial temperature range. The zero-drift architecture enables an offset voltage of 25 µV and offset-voltage drift of 80 nV/ºC. The chip generates only 250 nVpp of noise from 0,1 Hz to 10 Hz, and features a broadband noise floor of 12,5 nV/√Hz.
