Is this data available? The data sheet gives only typical value (35ppm/°C, theoretical "guaranteed by design") but no maximum. Any idea of how much would be this maximum? I am working with the 20K version.

Thanks in advance

Hi Rainier.

The problem is I am using it to ballance a differential amplifier. I have to use it as rheostat in that position thus knowing the TC is relevant for worst case analysis. Before you ask, no, I cannot use it in divisor mode in my design.

Relying on typical data for such an analysis is not exactly good engineering so I would like to avoid it if I can. Could you provide at least a reasonable ballpark for that figure? E.g.2x typical, 10x etc.?

Hi Elder,

The max TC can be estimated as twice of the typical specification which would be around 70ppm/degC.

Also take note that when using rheostat mode, the TC is not constant across all codes. See figure 24 on the data sheet for reference.

Best regards,

Rainier
