INA240-Q1: Questions regarding replace INA282 by INA240

Part Number: INA240-Q1
Other Parts Discussed in Thread: INA282, INA240

Hi team,

My customer wishes to replace INA282 by INA240 and have few questions regarding the datasheet spec, could you please help to clarify the following questions: 

1. Is it okay to left the NC pin of INA240 floating? INA282 datasheet specified NC can be either left floating or grounded, but INA240 datasheet only stated it should be grounded. 

2. The INA240 datasheet specified the maximum output capacitive load is 1nF. Is this maximum allowable load for the output or device internal capacitive load? My customer is connecting the output to a low-pass RC filter with 1k & 10nF. Is this acceptable? 

3. What are the setting time and slew rate for INA282? My customer wishes to compare these two values between INA282 and INA240, but INA282 datasheet did not specify these two values, whereas INA240 datasheet did.

4. What is the Voltage noise density test condition for INA240? Same 1kHz as INA282?


Please help to clarify the above questions.

Thank you very much.

Best Regards,
