MAX4190ESA+ Application Field and Working Principle

The MAX4190ESA+ is a dual video amplifier with low-voltage noise, wide bandwidth, and low phase distortion. It is designed for optimal video performance and is a high output, low supply current and low worry video amplifier solution.Application FieldThe fast rise time and wide bandwidth of MAX4190ESA+ make it an ideal product for composite video amplifiers and low noise oscilloscope preamps. It is also suitable for VGA, S-Video, and all types of vector-type video, including interlaced, progressive scan and flat panels.Apart from its electrical characteristics, the MAX4190ESA+ can also be used in applications like medical imaging, security cameras, and biometric sensor systems, providing outstanding performance and low distortion.Working PrincipleThe MAX4190ESA+ is composed of a precision, low-noise, wide-band two-pole amplifier with an adjustable output driver. A high-speed differential current-mode input stage increases the dynamic range and minimizes the effect of a potentially noisy power supply.The adjustable output driver supplies up to 80mA peak current to drive a 75ohm video load. The operating current is adjustable from 15mA to 50mA. It is also capable of supplying up to 400V peak-to-peak into a 75 ohm load.The MAX4190ESA+ provides an unmatched combination of low-noise, wide-band video performance, high output voltage capability, and low power consumption, perfect for use in high-performance video applications. It is capable of driving up to 75mV of output voltage swing with a supply voltage of 5V. It is also able to accommodate different loads and provides stable performance into a 75 ohm load at all supply voltages.ConclusionThe MAX4190ESA+ is a low energy, low voltage, low noise dual video amplifier with a wide bandwidth and low phase distortion. It is designed to accommodate different loads and provides stable performance into a 75 ohm load at all supply voltages. The device is suitable for composite video amplifiers, low noise oscilloscope preamps and medical imaging, security cameras and biometric sensor systems. Furthermore, its high output voltage capability and low-voltage noise make it the perfect choice for applications requiring high performance.
