INA128U/2K5 General Description

The INA128U/2K5 is a high-performance instrumentation amplifier that provides excellent accuracy and versatility in a small package. With a current-feedback input circuitry, it offers a wide bandwidth of 200 kHz at gain 100, making it suitable for a variety of applications. By using a single external resistor, users can easily set the gain from 1 to 10,000, providing flexibility in design. The INA128 comes with an industry-standard gain equation using a 50-kΩ resistor, while the INA129 allows for drop-in replacements with a 49.4-kΩ resistor

Key Features

Fast response time: 1.5 μs max
High sensitivity: 100 mV/Pa min
Precise calibration: ±1% FS max
Wide temperature range: -40°C to +85°C
Rugged design: meets IP67 and IPC ratings
Interchangeable sensors: modular design for easy upgrades
