INA236: No Bandwidth Specified for INA236 in Onlie search tool

Part Number: INA236
Other Parts Discussed in Thread: INA226

Hi,

In comparison table : https://www.ti.com/amplifier-circuit/current-sense/products.html

INA236 has no Bandwidth specified :

While INA 226 ( which has identical gain vs Frequency characteristic in the data sheet) has this BW specified as 3.5KHz. Is it intentional , is INA236 having less BW or is it a mistake in the online tool?

Kind Regards

Sebastian

Reading a bit more I realized teh BW is not down to gain vs Frequency graph but the low pass filter with notch frequency of 1/(2xConversion time). Since both INA226 and INA 236 have minimum conversion time of 140us it looks liek both have the same BW so it looks like the online tool needs an update?

Hi Sebastian,

I will reach out to the Systems engineer responsible for the datasheet and come back to you with an answer tomorrow.

Hi Sebastian,

It turns out we do not normally spec bandwidth for our digital power monitors. It was a mistake that we have that listed on our online tools. They are going to be working on removing that spec now. Thank you for bringing this to our attention!

Best,

Mohamed
