Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX9504A/MAX9504B 3V/5V, ground-sensing amplifiers with a fixed gain of 6dB provide high output current while consuming only 10nA of current in shutdown mode. The MAX9504A/MAX9504B are ideal for amplifying DC-coupled video inputs from current digital-to-analog converters (DACs). The output can drive two DC-coupled 150 back-terminated video loads in portable media players, security cameras, and automotive video applications. The MAX9504B features an internal 160mV input offset to prevent output sync tip clipping when the input signal is close to ground.
The MAX9504A/MAX9504B have -3dB large-signal bandwidth of 42MHz and -3dB small-signal bandwidth of 47MHz.
The MAX9504A/MAX9504B operate from a single +2.7V to +5.5V supply and consume only 5mA of supply current.The low-power shutdown mode reduces supply current to 10nA, making the MAX9504A/MAX9504B ideal for low-voltage, battery-powered video applications.
The MAX9504A/MAX9504B are available in tiny 6-pin DFN (2mm x 2mm) and 6-pin SOT23 packages, and are specified over the -40°C to +85°C extended temperature range.
