The INA155U is a low-cost CMOS instrumentation amplifier designed for single-supply operation with rail-to-rail output swing. It features a fixed gain of either 10V/V or 50V/V, which can be adjusted with an external resistor for intermediate values. The device operates over a supply voltage range of +2.7V to +5.5V and is specified for a temperature range of -55¬8C to +125¬8C. Key specifications include a low offset voltage of -200 mV, low input bias current of 0.2 pA, and a wide bandwidth of 550 kHz at a gain of 10. The high slew rate of 6.5 V/ms allows for effective use in applications requiring fast response times, such as driving A/D converters and audio processing. The INA155U is available in an 8-pin SOIC package, making it suitable for compact designs. This amplifier is ideal for various applications, including industrial sensor amplifiers, medical equipment, and automotive instrumentation, providing reliable performance in demanding environments.
