Hi ADI,
I have a question regarding the maximum gain of ADA4897-2 and capacitive loads.
I use this amplifier with a gain =50 to amplifiy the sensor signal at the input of AD7124-4.
I use 100 ohm snubber resistor comes after a 2.2nF capacitor also another…
Dear analog engineers,
I was looking in the datasheet of ADA4897.
There is an example of a low noise gain selectable amplifier with an extra switch in the datasheet.
In this example you placed an balance resistor, to get a more constant offset voltage…
There is a small error in ADA4897 spice model, where node 106 (PD) should be DISABLE bar, i.e., when 106 pulled to -VS + 0.7 V, AD4897 will be put into disable mode.
i am using ADA4897 as non inverting unity gain amplifier. i used function generator to provide the input to the opamp(dc voltage). when i try to measure the voltage at the input of non-inverting terminal(i/p), I could see some change in the o/p of opamp…
I have a standard inverting amplifier stage with Rf = 100k and Rg = 10k (A = -10 V/V). The amp is powered from +/-5V and the positive input terminal is connected to 0V. Pins 1 and 5 are open. Pin 8 (nDISABLE) is also left open. Very straightforward setup…
Hello,
In the datasheet of ADA4896/ADA4897 bias current is specified as -11uA (typ.). What "-" sign signifies? At first I assumed it signifies the direction of current flow as in "-" signifies current flowing out of the input pin and "+" signifies current…
I am using the above mentioned opamp as a unity gain amplifier and the opamp is powered from 5V supply (Single supply). I am seeing oscillations in the o/p if opamp when a dc or ac input is given to opamp. can any one suggest the reason. i have provided…
