Could you clarify what is the correct resolution of the AC impedance measurement when using the TAS642Q1EVM with Gain=1 and current=10 mA? The data sheet Table 4 gives a mapping of 0.2496 Ohms per code but the value shown in the PPC3 GUI is 0.262632. Neither of these seem to agree with the reported impedance by the PPC3. For example, I get a reported impedance of 3.6 Ohms when the value in register 0x15 is 15 giving a resolution of 0.2400 for CH1 or an open load impedance of 19.7 Ohms when the value in register 0x16 is 83 giving a resolution of 0.23735. Or are these all within the nominal AC impedance accuracy of +/- 15%?
