Internal reference, REFIN bypassed to AGND with a 0.1µF capacitor.
External +2.5V reference applied to REFIN.
Internal reference disabled. V_REFIN = 0, V_REFP = 3.25V, V_CML = 2.25V, and V_REFN = 1.25V.
Measured as the ratio of the change in midscale offset voltage for a ±5% change in V_AVDD using the internal reference.
IMD is measured with respect to either of the fundamental tones.
Specifies the common-mode range of the differential input signal supplied to the MAX1426.
Defined as the input frequency at which the fundamental component of the output spectrum is attenuated by 3dB.
V_REFIN is internally biased to +2.5V through a 5kΩ resistor.
