Please tell us the method of calculation for the gain value at below condition.【Condition】AGC: OffDIGITAL FINE CLAMP: ONInput signal: 1Vpp = amplitude voltage of Sync on Green video
It seems that the value becomes considerably low at gain = 1.Could you provide us the any information for that?
The various gain values for ADV7441A is mentioned in page-145 of the hardware manual. And also figure44 in the hardware manual shows a good block diagram of how the data can be gained or clamped.
The gain can be given by the formula but different chipset at /cfs-file/__key/communityserver-discussions-components-files/112/ADV739xProgramableDACGain.pdf DAC gain = ( (DAC current (mA) / Nominal DAC current (mA)) *100 ) - 100 Did you refer below thread? ez.analog.com/.../adv7441a-ad9388a-gain-for-analog-signals-with-separate-syncs
