The INA1H182-SEP is a radiation-tolerant, high-precision instrumentation amplifier that offers low power consumption and operates over a wide single-supply or dual-supply range. A single external resistor sets any gain from 1 to 10,000. The device has high precision as a result of super-beta input transistors, which provide low input offset voltage, offset voltage drift, input bias current, and input voltage and current noise. Additional circuitry protects the inputs against overvoltage up to ±40V.

The INA1H182-SEP is optimized to provide a high common-mode rejection ratio. At gain (G) = 1, the common-mode rejection ratio exceeds 90dB across the full input common-mode range. The device is designed for low-voltage operation from a 4.5V single supply, and dual supplies up to ±9V.

The INA1H182-SEP is available in an 8-pin VSSOP package.
