This parameter is not tested in production. It is guaranteed by design and device characterization.
Set externally either by discrete external components or a third- or fourth-generation codec. Any complex impedance
R1 + R2 || C between 150 Ω and 1400 Ω can be synthesized.
VITR transconductance depends on the resistor from ITR to VITR. This gain assumes an ideal 4.75 kΩ, (the
recommended value). Positive current is defined as the differential current flowing from PT to PR.
