I have a circuit with an AD8033 in voltage follower topology (gain=1), with Vs+=24V, Vs-=0V (GND).
The input signal is a positive sine of 10Vpp.
In figure 1, at frequency 100kHz, the output (blue) follows the input (yellow).
Figure 53 of the data sheet shows the simplified Input Stage of AD8033/34.
There are two input stages; the JFET input and the Bipolar Input.
The Input Overdrive Section discussed how the transition occurs between these two input stages and this is…
Original Question: troubles with SPICE models of AD8033 and AD8065 by qwerty1234
i am working with your open SPICE models of AD8033 and AD8065and i am having troubles with the voltage gain characterization.
I would like to reproduce the OPEN-LOOP…
This is a good question, the AD8034 is a dual FET input amplifier. The AD8033 is the single version, we typically dont build dual Spice models, we just use two AD8033 Spice models to get a AD8034. For your application I would recommend just using…
Need high CMRR as well. I am using AD8033 as the front end, need a fast difference amplifier with at least +-7.5 voltage so I don't have to match the resistors. You need to have laser trimmed resistor in the difference amplifier.
