The LM8261M5 is a family of quad operational amplifiers designed to provide precision amplification in instrumentation, signal conditioning, and data acquisition applications. It features a wide range of gain bandwidths and output voltages, high accuracy, low power consumption and excellent temperature stability. This makes it ideal for use in high precision, precision analog applications.

The device is based on a differential input stage with an offset voltage of typically 0.3mV and a precision gain setting. The input stage is followed by a current-feedback amplifier with a steady-state gain of 6 dB, providing fast settling times and a wide range of gain settings, enabling the amplifiers to be used as a wide-band gain amplifier, instrumentation amplifier and active filter.

Four separate output buffers amplify the signal from each amplifier, ensuring a fast settling time even with large output swings. A common mode feedback loop maintains good common mode rejection ratio and low input bias current in all gain conditions. Additionally, the LM8261M5 uses a temperature compensating technique for stable amplifier performance over time and temperature.

The LM8261M5 is designed for maximum performance over a wide operating temperature range of -40°C to +125°C. It offers single-supplied operation from a +1.8 to +7.0V supply, with peak output currents of typically 5 mA and supply current of <2mA (TS).

The LM8261M5 is ideal for analog signal acquisition and conditioning applications. Its high accuracy, wide gain bandwidth, low power consumption and excellent temperature stability make it suitable for use in environments where the user needs to reduce costs, while still obtaining the desired performance. It can also be used in automotive applications where temperature variations demand precision performance.

In conclusion, the LM8261M5 is a family of quad operational amplifiers designed for precision amplification in instrumentation, signal conditioning, and data acquisition applications. It features a wide range of gain bandwidths and output voltages, high accuracy, low power consumption and excellent temperature stability. This makes it an ideal choice for precision analog applications requiring high accuracy and low power consumption over a wide operating temperature range.
