MAXIM MAX9504A, MAX9504B Technical data

General Description

The 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 150Ω 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
µDFN (2mm x 2mm) and 6-pin SOT23 packages, and
are specified over the -40°C to +85°C extended tem­perature range.

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.

Note 1: All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.

Note 2: Voltage gain (A

) is referenced to the input offset voltage; i.e., an input voltage of VINwould produce an output voltage of

V
