Other Parts Discussed in Thread: LF411
Hi Dear,
I am using THS4531 in the quantity of 48 as the input buffer of ADCs. My input frequencies are less than 1.2MHz. The data sheet says that if RF = RG = 2 kΩ, RG to ground, and VOUT+ = 4V, 1mA current will flow through the feedback path to ground. If I increase the value of resistor the current will be decreased.
Can you please let me know that if I go for a resistor value of 10K or 20K, how much current will flow through the feedback path to ground? The current consumption for my application is quite critical and I want to decrease the current as much as possible.
Also, by changing the resistor value, will it effect the input of ADC, signal will be attenuated or increased?
I am anxiously waiting for the reply.
Thank you
Kind Regards:
Mohsin
