Detailed Description
The MAX9509/MAX9510 represent Maxim’s second
generation of DirectDrive video amplifiers that meet the
requirements of current and future portable equipment:
1.8V operation. Engineers want to eliminate the 3.3V
supply in favor of lower supply voltages.
Lower power consumption. The MAX9509/MAX9510
reduce average power consumption by up to 75%
compared to the 3.3V first generation (MAX9503/
MAX9505).
Internal fixed gain of 8. As the supply voltages drop
for system chips on deep submicron processes, the
video DAC can no longer create a 1VP-P signal at its
output, and the gain of 2 found in the previous gen-
eration of video filter amplifiers is not enough.
DirectDrive technology is necessary for a voltage mode
amplifier to output a 2VP-P video signal from a 1.8V
supply. The integrated inverting charge pump creates
a negative supply that increases the output range and
gives the video amplifier enough headroom to drive a
2VP-P video signal with a 150 load.
DirectDrive
Background
Integrated video filter amplifier circuits operate from a
single supply. The positive power supply usually cre-
ates video output signals that are level-shifted above
ground to keep the signal within the linear range of the
output amplifier. For applications where the positive DC
level is not acceptable, a series capacitor can be
inserted in the output connection in an attempt to elimi-
nate the positive DC level shift. The series capacitor
cannot truly level-shift a video signal because the aver-
age level of the video varies with picture content. The
series capacitor biases the video output signal around
ground, but the actual level of the video signal can vary
significantly depending upon the RC time constant and
the picture content.
The series capacitor creates a highpass filter. Since the
lowest frequency in video is the frame rate, which can be
from 24Hz to 30Hz, the pole of the highpass filter should
ideally be an order of magnitude lower in frequency than
the frame rate. Therefore, the series capacitor must be
very large, typically from 220F to 3000F. For space-
constrained equipment, the series capacitor is unac-
ceptable. Changing from a single series capacitor to a
SAG network that requires two smaller capacitors only
reduces space and cost slightly.
The series capacitor in the usual output connection
also prevents damage to the output amplifier if the con-
nector is shorted to a supply or to ground. While the
output connection of the MAX9509/MAX9510 does not
have a series capacitor, the MAX9509/MAX9510 will
not be damaged if the connector is shorted to a supply
or to ground (see the
Short-Circuit Protection section).
