The MAX4090AAXT+T is a high-performance video amplifier designed for use in CCTV, automotive, medical imaging and imaging systems for the industrial application field. This amplifier can deliver up to 160 mV/V peak-to-peak gain and features an extremely low voltage noise floor of 0.2 µV/√Hz. The MAX4090AAXT+T is an excellent choice for a wide range of industrial applications that require a low noise, low distortion and reliable performance.

The MAX4090AAXT+T utilizes a low-dropout, charge-pump bias circuit to ensure a wide gain range and low dropout voltage. This bias circuit also eliminates the need for an external voltage reference to maintain a constant gain setting. The MAX4090AAXT+T operates over a wide range of input voltages (2.25 V to 20 V) and has a wide bandwidth of 45 MHz with a gain flatness of 1 dB. The amplifier also features an adjustable output slew rate of up to 10 MHz and an adjustable output current limit of up to 1 A.

The MAX4090AAXT+T utilizes a capacitive input for signal isolation and impedance matching, and a low-noise, low-offset, rail-to-rail output amplifier stage. The MAX4090AAXT+T also features a maximum sampling rate of 1 MSps and a low power consumption of 4 mA. The amplifier also features an input port that is protected from high-voltage transients.

The MAX4090AAXT+T features an adjustable gain and a maximum output voltage of 20 V. The amplifier can deliver a noise performance of 75 dBc typical at 1 MHz, and a maximum distortion of 0.1% at 6 MHz. The MAX4090AAXT+T can be powered with a single +5V supply or dual +12V/-5V supplies with an additional charge pump capacitor. The amplifier also includes a low power shutdown mode, which reduces the supply current to only 0.06 mA.

The working principle of the MAX4090AAXT+T is relatively simple. When a signal is applied at the input port, it is amplified by the amplifier and output at the output port. The gain of the amplifier is set with the gain adjustment pin. The gain and the output voltage are proportional to each other, so the output voltage can be increased or decreased by changing the gain setting of the amplifier. In addition, the MAX4090AAXT+T also features an adjustable output current limit, which limits the maximum output current of the amplifier.

The MAX4090AAXT+T is an excellent choice for a variety of applications in the industrial and imaging fields, where a low noise, low distortion and reliable performance are required. This high-performance video amplifier is also capable of delivering up to 160 mV/V peak-to-peak gain and features a very low voltage noise floor, making it suitable for a wide range of applications.
