MAX1126
Quad, 12-Bit, 40Msps, 1.8V ADC with
Serial LVDS Outputs
6 _______________________________________________________________________________________
Note 1: Specifications at T
A ≥ +25°C are guaranteed by production testing. Specifications at T A
< +25°C are guaranteed by design
and characterization and not subject to production testing.
Note 2: See definition in the Parameter Definitions section.
Note 3: The MAX1126 internally sets the common-mode voltage to 0.6V (typ) (see Figure 1). The common-mode voltage can be
overdriven to between 0.55V and 0.85V.
Note 4: Limited by MAX1127EVKIT input circuitry.
Note 5: Connect INTREF to GND directly to enable internal reference mode. Connect INTREF to AV
DD directly to disable the internal
bandgap reference and enable external reference mode.
Note 6: Data valid to CLKOUT rise/fall timing is measured from 50% of data output level to 50% of clock output level.
Note 7: Guaranteed by design and characterization. Not subject to production testing.
ELECTRICAL CHARACTERISTICS (continued)
(AV DD = 1.8V, OV DD = 1.8V, CV DD = 1.8V, GND = 0, external V REFIO = 1.24V, INTREF = AV DD , C REFIO to GND = 0.1µF,
f CLK = 40MHz (50% duty cycle), DT = 0, T A = T MIN to T MAX , unless otherwise noted. Typical values are at T A = +25°C.) (Note 1)
