MAX1126

Quad, 12-Bit, 40Msps, 1.8V ADC with
Serial LVDS Outputs

_______________________________________________________________________________________

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.
