Note 1:
Internal reference, REFIN bypassed to AGND with a 0.1µF capacitor.
Note 2:
External +2.5V reference applied to REFIN.
Note 3:
Internal reference disabled. V

Note 4:
Measured as the ratio of the change in midscale offset voltage for a ±5% change in V
AVDD
using the internal reference.
Note 5:
IMD is measured with respect to either of the fundamental tones.
Note 6:
Specifies the common-mode range of the differential input signal supplied to the MAX1426.
Note 7:
Defined as the input frequency at which the fundamental component of the output spectrum is attenuated by 3dB.
Note 8:
V
REFIN
is internally biased to +2.5V through a 5k
Ω resistor.
