INA211: swing to gnd ZERO

Both the WS74199 and the INA211 have outputs that can go near GND when the output current is small enough.

What is the actual output current in your application? If it is more than a few microamperes, you can use a negative bias generator like the LM7705.

Hello Alice,

It looks like the INA211 beats the WS74199Q-10 on all the metrics that I checked. I noticed that it has a worse swing to GND specification than the INA211. Also, as Clemens mentioned, a negative bias generator such as the LM7705 can be used to shift the operating range of the device below the GND level for feeding the output into precision measurement circuitry. The Vref pin of the INA211 can also be used to move the zero-point of the amplifier up to a know reference if the subsequent signal chain is able to accept this input.

Let me know if you have any more questions,

Alice,

Based on the specs in the competitors data sheet as well as the part numbering, the INA199 would be the more appropriate cross rather than the INA21x family of devices.
