Internal reference, REFIN bypassed to AGND with a 0.1µF capacitor.
External +2.5V reference applied to REFIN.
Internal reference disabled. VREFIN = 0, VREFP = 3.25V, VCML = 2.25V, and VREFN = 1.25V.
Measured as the ratio of the change in midscale offset voltage for a ±5% change in VAVDD 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.
VREFIN is internally biased to +2.5V through a 5kΩ resistor.
