In this project, we used Linear's high speed ADC LTC2175, LT6409(SE~Difference) as the driver. AD8039 as the first level amplifier and follower. Signal input Range: ±0.5V~±5V (i.e. Gain: 1~10); Input Freq: DC~60 MHz; When the input signal of AD8039 connected…
AD8039 can work with a single power supply?
According to its data sheet, the supply range is 3V to 12V but my AD8039 output 1V under 0V input and 5V single power supply condition. It works correctly (output=0V) by changing +/- 5V supply.
AD8039 and AD8099 do have phase reverse protection?
I have problem with Absolute Maximum Ratings of AD8039. The Differential Input Voltage is limited to +-4V.
May I apply a slightly higher voltage if I limit the current with the series resistor?
In my circuit I have ADA4897 Rail-to-Rail output amplifier…
Highest signal frequency 140KHz.
AD8039 is specified by Filter Wizard tool.
Layout follows recommendations in AD8039 data sheet.
If necessary I will deal with any instability issues later.
My main concern now is the DC levels. I was expecting…
"Name": "40kHz BP",
"Description": "Center 40kHz\nPass 60kHz\n4 order",
I'm using the Filter Wizard tool: Filter Wizard | Analog Devices to design a high pass filter, my amp is single power supplied, and the wizard adds a reference voltage generation circuit using AD8031.
