Digital Potentiometer +-15V

Other Parts Discussed in Thread: UA741

I'm looking for a 6 channel digital potentiometer that can handle with voltages +/- 15V or more. Does anyone knows any that meet the requirements? Thanks in advance.

All TPLxxxx devices have ESD protection diodes (limiting voltage levels to VCC/GND), and their supply voltage range is smaller.

What do you need it for? Might it be possible to use opamps to amplify the signals?

Its for using as RF of a UA741 (OPAMP). I need to change the value of the RF and, even with small input voltages, I could have about 15V.

Hi Paulo,

Our TPL devices typtically range from 2.7 V to 5.5 V and the max number of Potentiometers we have in 1 package are 2 potentiometers.

Thanks,
Siby

I was looking for something like AD5206 but with larger range Bx: -15V - Ax: 15V. Thanks anyway for the replies.
