Part Number: OPA2171
Other Parts Discussed in Thread: TLV9002, TLV9062, OPA2990

Hi team,

When I read the OPA2171 datasheet, there are different descriptions about the power supply range.

1. Features:

2. Recommended ranges:

So my custoemr wants to use singe 3.3V power supply. Is it OK for OPA2171?

Best regards,

Wayne

    Hi Wayne,

    Yes, this device is operational for single 3.3V supply. Please be aware that this is a high-voltage device. If your customer intents to use single supply 3.3V, then I would recommend looking into TLV9002 or TLV9062 (low-voltage parts)

    Please find the comparison below:

    Best Regards,

    Hi Wayne,

    Not all specifications are specified with a supply voltage at 2.7V. For example, Aol, PSRR, and CMRR all have test conditions using at least a 4V supply.

    If the customer requires a high voltage device specified down to 2.7V I recommend taking a look at the OPA2990.

    Thank you,
