MAX9504AEUT+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
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 shut-
down mode. The MAX9504A/MAX9504B are ideal for
amplifying DC-coupled video inputs from current digi-
tal-to-analog converters (DACs). The output can drive
two DC-coupled 150Ω back-terminated video loads in
portable media players, security cameras, and automo-
tive 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 cur-
rent. 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 tem-
perature range.
