The MAX4402ASA-T is a special type of linear amplifier which is classified under the instrumentation, OP amps, and buffer amps categories. It is designed specifically for low-voltage and portable applications which require the amplification of signals without distortion.

Maxim Integrated’s MAX4402ASA-T micropower amplifier contains a single-supply amplifier designed for supplying up to 8 mA of drive current and has a 3 dB bandwidth of 90MHz when operated from a single 3V supply. This amplifier can be implemented in a wide array of low-voltage applications such as portable medical and test instrumentation, precision analog signal processing, and RF communications.

The MAX4402ASA-T is an enhancement type amplifier which provides an output signal that is three times that of the input. This attribute makes it suitable for applications requiring a signal gain of 3 dB or less. Its linear ranges from 3 MHz to 8 MHz while its input range is specified between +2.5V and 1.6V. Maxim Integrated’s micropower amplifier provides an output signal that is approximately two times the input for amplitudes between 1.4V and 1.2V, and the amplitude at the output is approximately one-third of the input for amplitudes below 1.2V.

The MAX4402ASA-T micropower amplifier provides a gain of 18 dB at the lower end of the frequency range and a gain of 24 dB at the higher frequencies. Its output-to-noise ratio is 96 dB, which ensures that very little of the input signal is lost in the amplification process. Its power consumption is very low, and it can operate with a power supply voltage as low as 1.8V.

This amplifier from Maxim Integrated features very strong current-gain of with an excellent temperature stability. Its input resistance and capacitance are specified at 2k ohms and 1pF respectively and its output resistance is approximately 50 ohms. Its quiescent current is in the range of 3.2mA at the 3V supply. The MAX4402ASA-T also features an internal thermal limiting safety system which shuts itself off when it reaches a temperature above the specified limit.

Maxim Integrated’s MAX4402ASA-T is a very efficient device which is suitable for a wide range of applications. It can help to increase the signal strength of a low-voltage system and can also be used in other environments where the amplification of weak signals is required. Because of its low power consumption, it is particularly well-suited for battery-powered applications.
