Hi
A circuit is being designed to read the FET current value using the Current Sense Amplifier within the DRV8323HS.
We are going to use 5V/V gain and want to limit bandwidth by applying RC primary LPF to SOx which is sensor output pin. (approximately 300 kHz)
However, there is a lack of information on the output of the Amplifier on the DRV8323HS Datasheet, which makes the design difficult.
(Output impedance, open loop gain, output current, etc…)
In this regard, I would like to request you to review the following inquiries.
1. Is it possible to provide data such as output impedance, output current, open loop gain, and gain frequency response graph of DRV8323HS?
2. Can primary LPF using 56 ohms, 10nF have a bandwidth of about 300 kHz when configuring it? (Considering the amplifier output characteristics of DRV8323HS)
3. Is there a way to infer output characteristics using Unity Gain bandwidth?
Thanks
