The MAX9242EUM+D is an ultra-low power, high-speed current feedback amplifier designed primarily for use in video applications. The device consists of an operational amplifier with a current-feedback architecture, a voltage-feedback architecture, and a patented dynamic limiting predefined by a fixed resistor. The MAX9242EUM+D offers superior audio performance, providing high circuit gain, wide bandwidth (maximum –3dB pro‐vided at 9MHz), low power consumption (2.6mW maximum), and low distortion (–90dB maximum THD). Its high-current, single-ended output stage offers fast settling and low output noise.

The primary application field for the MAX9242EUM+D is in video applications, such as Audio video receivers (AVRs), flat panel displays, video scalers, and DVD players. It can also be used in audio sub-systems, such as laptop PCs, digital cameras, and HD Camcorders. The MAX9242EUM+D allows for high performance across a wide variety of video applications. It has been designed to provide high channel separation in stereo systems, due to its novel architecture that limits the bandwidth of the feedback network.

The MAX9242EUM+D uses current feedback to achieve superior audio performance. The current-feedback amplifier architecture combines a low output impedance with stable gain and excellent bandwidth. It also provides a wide bandwidth and low-distortion performance. The current feedback amplifier dissipates less power than its voltage-feedback counterpart, making it more suitable for applications with highly sensitive input signals. The MAX9242EUM+D also has a patent-pending dynamic limiting feature, which compensates for any nonlinearities in the system and reduces total harmonic distortion (THD).

The low power consumption of the MAX9242EUM+D means it is ideal for use in low-power applications. The device draws a maximum current of only 2.6mW. This improved efficiency makes the device particularly suited for use in personal audio systems, such as Bluetooth speakers, and for applications in automotive and consumer markets.

In addition to its low power consumption, the MAX9242EUM+D is designed for a wide variety of temperature ranges, allowing it to operate under extreme temperature conditions. The device is available in 2mm X 2mm WQFN (0.8mm pitch) package. This ensures the lowest possible parasitic capacitance and highest stability.

The MAX9242EUM+D is a high performance, low power, and highly reliable solution for audio video applications. It provides superior audio performance, fast settling, low output noise, excellent bandwidth, low distortion, and low power consumption. Its wide temperature range, low-parasitic capacitance package, and patented dynamic limiting feature make it an ideal solution for video applications.
