MAX457EPA is a high-performance video amplifier module designed to enhance video signals. It has a typical slew rate of 100V/µs and a video bandwidth of 10 MHz and provides excellent video reproduction and clarity, making it an ideal choice for most video applications. The amplifier is designed to provide a low offset voltage, low distortion and an adjustable gain of up to 30dB.

The high performance of the MAX457EPA is achieved by its patented single-stage gain cell which combines DC voltage gain and AC video gain. This design allows the amplifier to be used in many different video amplifier applications, including those that require low-noise, high-gain performance with low distortion and low power consumption. The amplifier also features an adjustable gain range of 0 to 30 dB, enabling the user to easily adjust the amplifier’s gain to suit their application.

The MAX457EPA uses a positive/negative (+/-) power supply, typically ranging from +9V to ± 18V, allowing the amplifier to drive larger loads with low distortion and low power consumption. This allows the amplifier to be used in both AC- and DC-coupled video amplifier designs. The amplifier also features a low noise figure of 1.8 dB or less. This low noise figure helps ensure that the amplifier will provide clear video signals with little noise or distortion.

The MAX457EPA also features a slew rate of 100V/µs, allowing the amplifier to drive high-frequency video signals. Its video bandwidth of 10 MHz helps to ensure that the amplifier will reproduce signals accurately with no signal degradation.

The module has a minimum input differential voltage of 1.5V and a maximum differential voltage of ± 20V. The output voltage range is typically 1V to ± 15V, with a maximum output current of 50 mA. The MAX457EPA also features a common-mode rejection ratio (CMRR) of 70 dB or better, a gain flatness of 0.2 dB or better, and a supply current of 18 mA.

The MAX457EPA is designed to be simple to use, with adjustable gain, output offset, and power supply voltage. It is suitable for use in many video amplifier applications, including LCD displays, video cameras, and video mixers.

In summary, the MAX457EPA is a high-performance video amplifier module that offers excellent video performance with low distortion, low power consumption, and adjustable gain. It is suitable for many video applications, including LCD displays, video cameras, and video mixers. With its low noise, high slew rate, and adjustable gain, the MAX457EPA is an ideal solution for many video amplifier applications.
