MHW8267AN

The MHW8267AN is a high performance, fully differential video amplifier, manufactured by the Hitachi company. This device is part of the Linear-Amplifiers-Video Amps and Modules product line. It offers an excellent combination of very low noise, distortion, and power consumption, making it a great choice for high speed video applications in consumer electronics.

The MHW8267AN is designed to drive high quality video signals. It does this by amplifying, simultaneously, two channels of 2.8Vpp video signals, thus outputting two differential, 1.4Vpp video signals with an extremely high performance rating of less than 1dB of noise. Additionally, it offers a gain ratio from +2 to +16.

Due to its high output capability and low noise level the MHW8267AN continues to be the amplifier of choice for many professional and consumer video products. It is used in a variety of applications, including VTR, HDTV, DVD recorders, LCD displays, projectors, HDTV converters, set-top boxes and more. In addition, due its low power consumption, it is often found in portable devices such as smartphones, tablets and even television remotes.

The MHW8267AN works by amplifying incoming video signals using a fully differential amplifier configuration. Using the differential circuitry ensures that any common mode noise is fully rejected. This creates a high noise immunity and provides a clean, stable output. It also allows for higher output voltages and better performance.

The heart of the MHW8267AN is the differential amplifier. The differential amplifier is an amplifier designed to provide balanced outputs from unbalanced inputs. It is comprised of two devices, a pair of transistors that act as amplifiers, with the inputs and outputs arranged in a differential configuration. The differential input signals drive the amplifier to provide the output voltage.

The differential inputs of the MHW8267AN are comprised of two separate pins for the two channels. The video signals are applied directly to the inputs, and the amplified output is available across the same pins. The differential architecture of the amplifier ensures that any common mode noise present in either input is significantly suppressed, while any differential information contained in the input signal is amplified and preserved.

The MHW8267AN also utilizes structural measures to further reduce noise and distortion. This includes an advanced feedback topology, which reduces distortion and noise, and a notch filter, which helps suppress interfering noise. This combination of technologies allows the amplifier to provide a very high quality output.

The MHW8267AN is a well-designed amplifier, providing high quality video signals with very low noise, distortion and power consumption. It is widely used in video applications for consumer and professional electronics, and continues to be the amplifier of choice for many companies.
