OPA2544: Supply voltage and the maximum output swing

Lacey Lin

Part Number: OPA2544

Hi Team,

My customer are looking for a amplifier which can output the signal with the voltage larger than 50V.

So I have found that the OPA2455 can support the ±35V supply voltage, and can swing to Vcc-+1 and Vcc+-1V.

1.Can the OPA2455 support the signal supply voltage like Vcc-=0V and Vcc+=60V and output swing to 50V?

2. Is there any other amplifier can support more than 50V output swing? with 2 channel.

Lacey

Thanks a lot!

    Hello Lacey,

    Regarding your OPA2544 questions:

    1. Can the OPA2455 support the signal supply voltage like Vcc-=0V and Vcc+=60V and output swing to 50V?

    The OPA2544 can be used with a single +60 V supply, where V+ is +60 V and V- is at 0 V, or GND. The limitations would be that the output voltage range would be from approximately (V-) + 5 V to (V+) - 5 V, or +5 V to +55 V, for a 2 Amp load. It will be a little wider for lower load current. And the input voltage range would be limited to the input common-mode voltage range of (V–) +6 V minimum, or (V–) +4 V typical on the bottom end, and (V+) –6 V minimum, or (V+) –4V typical, on the high end. Using the minimum values the linear input voltage range would be +6 V to +54 V, with a +60 V supply.

    2. Is there any other amplifier can support more than 50V output swing? with 2 channel

    The OPA2544 is our only dual high-voltage, high-current operational amplifier.
