Description for the INA128

The INA128 and INA129 (INA12x) are low-power, general-purpose instrumentation amplifiers that offer excellent accuracy. The versatile three op amp design and small size make these amplifiers an excellent choice for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100).

A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain equation with a 50-kΩ resistor. The INA129 gain equation uses a 49.4-kΩ resistor to allow for drop-in replacements of comparable devices.

The INA12x are available in plastic DIP and surface-mount packages, specified for the –40°C to +85°C temperature range. The INA128 is also available in a dual configuration, the INA2128.

The upgraded INA828 offers a lower input bias current (0.6 nA, max) and lower noise (7 nV/√Hz) at the same quiescent current. See the Device Comparison Table for a selection of precision instrumentation amplifiers from Texas Instruments.

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.
