Texas Instruments (TI) 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 used in the INA188 delivers high accuracy for high-voltage precision-measurement applications. Compared to competitive solutions, it enables an offset voltage of 25 μV and a 33 percent lower offset-voltage drift of 80 nV/oC to provide long-term temperature stability over the lifetime of the end equipment.
The INA188 generates only 250 nVPP of noise from 0.1 Hz to 10 Hz, with no 1/f corner frequency between broadband and near-DC. When combined with the INA188's broadband noise floor of 12.5 nV/√Hz, the amplifier provides unrivaled precision for low-frequency applications.
Capable of operating at up to 36 V, the INA188 helps maintain signal integrity over the full extended temperature range by allowing larger gains than lower voltage instrumentation amplifiers.
Features:
－ Industry's lowest offset drift optimizes long-term temperature stability
－ No 1/f corner and low DC noise enable precise measurements at low frequencies
－ High voltage ensures signal integrity
