PGA204: Single Ended Use

Part Number: PGA204
Other Parts Discussed in Thread: PGA205

Hi Team,

Can the PGA205 be used with a single ended input? I looked in the datasheet to see if there was an application circuit for this use, but did not see one. 

If it can be used with a single ended input, is there an example application circuit i can follow?

Thank you,

Jared

    Hi Jared,
    Yes, PGA205 could be used with a single-ended signal, so long as the input common mode voltage remains within the specified range (±10.5V min on ±15V supplies). For a single-ended signal, you'd ground the VIN- pin and apply your signal of interest to the VIN+ pin, as shown in Figure 9 of the datasheet.
