MAX9509, MAX9510
1.8V, Ultra-Low Power, DirectDrive Video Filter Amplifiers
Industry's First 1.8V, Ultra-Low-Power Video-Filter Amplifier Operates from Digital 1.8V Supply, Simplifying Circuitry
|
Status
Active: In Production.
Description
Operating from a 1.8V single power supply, the MAX9509/MAX9510 amplify standard-definition video signals and
only consume 5.8mW quiescent power and 11.7mW
average power. The MAX9509/MAX9510 leverage
Maxim's DirectDrive™ technology to generate a clean,
internal negative supply. Combining the internal negative
power supply with the external positive 1.8V supply,
the MAX9509/MAX9510 are able to drive a 2VP-P
video signal into a 150Ω load.
Besides increasing the output voltage range, Maxim's
DirectDrive technology eliminates large output-coupling
capacitors and sets the output video black level near
ground. DirectDrive requires an integrated charge pump
and an internal linear regulator to create a clean negative
power supply so that the amplifier can pull the sync
below ground. The charge pump injects little noise into
the video output, making the picture visibly flawless.
The MAX9509/MAX9510 are designed to operate from the
1.8V digital power supply. The high power-supply rejection
ratio (49dB at 100kHz) allows the MAX9509/MAX9510 to reject the noise from the digital power supply.
The MAX9509 features an internal reconstruction filter
that smoothes the steps and reduces the spikes on the
video signal from the video digital-to-analog converter
(DAC). The reconstruction filter typically has ±1dB
passband flatness of 8.1MHz and 46dB attenuation at
27MHz. The large-signal, ±1dB passband flatness of
the MAX9510 video amplifier is typically 8.4MHz, and
the large signal -3dB frequency is typically 11.4MHz.
The input of the MAX9509/MAX9510 can be directly
connected to the output of a video DAC. The MAX9509/MAX9510 also feature a transparent input sync-tip clamp, allowing AC-coupling of input signals with different DC biases. The MAX9509/MAX9510 have an internal
fixed gain of 8. The input full-scale video signal is
nominally 0.25VP-P, and the output full-scale video signal
is nominally 2VP-P. The devices operate from a 1.8V
or 2.5V single supply and feature a 10nA low-power
shutdown mode. The MAX9509 is offered in an 8-pin
TDFN package and the MAX9510 is offered in an 8-pin
µMAX® package.
