I am using AD811AN(8 pin PDIP package) video amplifier for my ultrasound receiver signal amplification process.
I have attached reference schematic.
i operate AD811 in dual power supply mode. that is +/-12V.
i have studied datasheet of AD811. in datasheet there is some recommendation for resistor values that can be used for amplification.
i have used those resistors.
at the output, i have put the CRO probe for output signal analysis.
but the problem is when i switch on both power supply, AD811 is getting heated.
power dissipation will be = (24Vx16mA = 0.384W)
My questions are as below:
1) How can i dissipate heat safely for AD811AN(8 pin PDIP package)? can i use heat sink ?
2) Which are the new CFB Op-Amps which are better then AD811 & can operate on +/-12V & no heat dissipation problem occur(if possible)
3) how can i use VGA for my ultrasound receiver signal amplification process?is any document is there then give me the link.
