EOC falls at the completion of a RESET

calibration cycle in microprocessor mode

only. In microprocessor-independent mode

cycles after completion of a RESET calibration.

The device acquires and converts in 64

CLKIN cycles for CLKIN=4MHz, but will

require 68 CLKIN cycles at 100kHz through-

put. This is due to excess delay on

CS5012A

15 bits. Results in DNL calibration

to 1/8 LSB at 12 bits.

58,280 CLKIN cycles

2,014 conversions

fully functional

EOC falls in either microprocessor

or microprocessor-independent

mode at the completion of a RESET

calibration cycle.

The device acquires and converts

a sample in 64 CLKIN cycles for all

CLKIN frequencies when in loopback.
