Description for the INA188

The INA188 is a precision instrumentation amplifier that uses TI proprietary auto-zeroing techniques to achieve low offset voltage, near-zero offset and gain drift, excellent linearity, and exceptionally low-noise density (12 nV/√Hz) that extends down to dc.

The INA188 is optimized to provide excellent common-mode rejection of greater than 104 dB (G ≥ 10). Superior common-mode and supply rejection supports high-resolution, precise measurement applications. The versatile three op-amp design offers a rail-to-rail output, low-voltage operation from a 4-V single supply as well as dual supplies up to ±18 V, and a wide, high-impedance input range. These specifications make this device ideal for universal signal measurement and sensor conditioning (such as temperature or bridge applications).

A single external resistor sets any gain from 1 to 1000. The INA188 is designed to use an industry-standard gain equation: G = 1 + (50 kΩ / RG). The reference pin can be used for level-shifting in single-supply operation or for an offset calibration.

The INA188 is specified over the temperature range of –40°C to +125°C .

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
