AD8510 and capacitive loads

Question asked by SteffenH on Apr 8, 2013

I use the AD8510 in unity gain configuration as DAC buffer. The resistive load at the output is 10kOhm and there is also a capacitive load due to cable capacitance in the range of 1 - 2nF. Which compensation method for the capacitive load would you recommend? To preserve DC accuracy I won't use a output series resister larger than 5Ohms. The compensation method should preserve DC accuracy and it should be able to cope with 1nF

as well as 2nF capacitive load.

 

I have an additional question about snubber networks to compensate for capacitive loads: is the order of the capacitor/resistor series connection relevant? Does it have to be op amp output --> resistor --> capacitor --> ground, or is op amp out --> resistor --> capacitor --> ground also ok?

Steffen
