TDA1543 I/V Resistor = 1v RMS

[vizion]

Hi Peeps,

What resistor value is needed to yield 1v RMS from a 1543 NOS DAC ? I think the Starting Point DAC also has an output of 1v RMS

thanks in advance.

The data sheet says the full scale current is 2.3 mA.

1.25k (use ohm's law) but not sure it would be a very good idea, AC output compliance is given as only 50mV peak to peak.
