The MAX4289ESA+ is an instrumentation linear amplifier. It is a low-voltage, rail-to-rail output opamp with low power consumption, wide bandwidth, and 10V/µs slew rate. The gain bandwidth product (GBWP) of this amplifier is 6.5MHz and it has a maximum supply voltage of 16V. The amplifier also has a high output current (3mA) with a low distortion of less than 0.01%.

The MAX4289ESA+ is well suited for a variety of battery-operated applications including audio, industrial control systems, data acquisition, and instrumentation. The rail-to-rail output allows the amplifier to be used in low voltage applications as it eliminates the need for level shifting circuitry to bridge the gap between the lowest and highest supply voltage. Its wide bandwidth makes it an ideal choice for high speed GByte applications such as active filters and data converters.

The MAX4289ESA+ offers wide supply voltage operation and superior distortion and noise performance. It features a low input bias current of 250nA, low voltage noise of 9nV/sqrt-Hz, and low supply current of 8mA. Its very low supply current helps improve the efficiency of battery-operated systems by reducing total system power.

The MAX4289ESA+ uses a common-source output stage topology which provides rail-to-rail output swing with low distortion and wide bandwidth. A special input stage allows virtually all operating parameters to remain constant over the full temperature range. This includes gain, noise, and supply current characteristics. The common-source output stage also allows for phase reversal and improved output current, improving dynamic range and reducing distortion.

The MAX4289ESA+ is an excellent choice for low voltage, low power, and high precision applications. Its wide bandwidth and low distortion make it ideal for high speed analog signal processing, while its low supply current and low bias current make it suitable for battery operated systems. The common source output stage provides a high output current and rail-to-rail output swing, helping to reduce distortion and improve dynamic range. When used in applications such as audio, industrial control systems, data acquisition, and instrumentation, the MAX4289ESA+ provides superior performance and reliability.
