THEORY OF OPERATION
The SPT5240 is a 10-bit 400 MWPS digital-to-analog con-
verter implemented in 0.25 m CMOS technology. It inte-
grates a DAC core with a bandgap reference and operates
from a +3.3-volt power supply.
The DAC architecture is a compound differential current
output DAC consisting of a 6-bit fully segmented DAC for
the MSBs and a 4-bit fully segmented DAC for the LSBs.
The input cell, followed by a master-slave latch, buffers the
digital inputs. A 6:64 decoder decodes the digital data for
the MSBs, and a 4:16 decoder does so for the LSBs. The
outputs of the decoders are latched using a second bank
of master-slave latches whose outputs then drive differen-
tial current switches, which steer the appropriate current to
the IOP or ION outputs.
The analog (AVDD) and digital (DVDD) power supplies are
separated on chip to allow flexibility in the interface board.
The analog (AGND) and digital (DGND) are separated on
chip. Circuit board ground planes should be separated and
tied together with a ferrite bead.
