The MAX4461UESA is a family of low-noise operational amplifiers designed to honor the distortion and noise specifications in applications that demand high-performance audio. The MAX4461UESA amplifiers feature low-noise, broad frequency response, high slew rate, an input common mode range that extends down to ground, and an output swing that surpasses the supply rails. These op amps come in dual and single configurations, and are characterized as linear amplifiers and instrumentation amplifiers. They are also suitable for use as OP amps, buffers, and general-purpose amplifiers.

The MAX4461UESA series draws on the production-proven architecture of the legacy TLE and MAX4460 families and integrates a number of design innovations to improve performance in critical applications. The result is a more efficient amplifier with lower distortion and noise. The gain bandwidth product for the devices is typically 90 kHz at a gain of +6 V/V. The MAX4461UESA series are available in 8-pin SOIC, 8-pin DIP, and 8-pin MSOP packages and offer very low power consumption of 1.2 mW/amplifier. Notably, the input common mode voltage range of each device extends to ground and the output voltage swing ranges further than the supply rails.

The MAX4461UESA is a versatile amplifier and the overall performance, size, and power requirements make it suitable for use in many demanding applications. It is commonly used in audio line inputs, gain blocks, microphone pre-amps, semi-parametric equalizers, and instrumentation amplifiers. The device works well in systems requiring low voltage rail to rail amplifier capability and robust distortion performance, such as portable audio applications. The device can also be used to drive both low and high impedance loads. The MAX4461UESA family is also known for its low power operation and very close board layout requirements.

The MAX4461UESA family of operational amplifiers operates by amplifying the difference between two input voltages. This process is known as differential amplifying. The device contains two inputs—an inverting input and a non-inverting input. The inputs are internally connected to a differential amplifying stage using a complementary symmetrical pair of transistors. The output voltage rests at a voltage equal to the input voltage multiplied by the gain of the device. The maximum gain of the amplifier is limited to the maximum value determined by its design. Each device also has a current-limiting feature that prevents it from outputting more current than it can handle.

The MAX4461UESA family of amplifiers is capable of operating over a wide range of frequencies, due to its low-noise and wide frequency response. The device has an excellent signal-to-noise ratio, and is capable of operating up to 1.2MHz bandwidth. It is also has an impressive slew rate of 16V/µs, which helps to make it fast and efficient. The input common mode voltage range of each device extends to ground, and the output voltage swing ranges further than the supply rails.

The MAX4461UESA devices is suitable for many demanding applications. Its low power consumption and small size makes it ideal for portable applications, such as battery-powered audio equipment. It also offers excellent linearity and only requires very close board layout. It is great for audio line inputs, gain blocks, microphone pre-amps, semi-parametric equalizers, and instrumentation amplifiers, as well as general-purpose amplifiers and single supply operated op-amps. This versatile device is ideal for applications where high performance, low noise, and power efficiency are key.
