Part Number: TPS8804
Other Parts Discussed in Thread: TPS8802

Hi Team,

We have some questions on smoke detector application as below:

1. My customer is asking for input range 3V-5V smoke detector AFE solution. Do we have better suggested solution?

2. in TPS8804 EVM BOM, we don't have CO sensor part number. Could you share it and how do we choose a suitable CO sensor?

3.  Do IRLED and Photodiode have limitation on distance of placement?

Best regards,

Hardy
