It delivers a 1.3 MHz -3 dB bandwidth with a 4V/µs slew rate, drawing 700 µA supply current.
Standard INA128 parts top out at 85°C or 125°C; the HD suffix extends the junction temperature to 175°C, making it suitable for downhole drilling instrumentation, engine-mounted sensors, and satellite avionics where ambient heat exceeds conventional limits.
The primary difference is the operating temperature range: the INA128HD extends to 175°C, while standard INA128 variants are typically rated to 85°C or 125°C. The HD suffix indicates the wider-temperature-grade die and package qualification.
