When WR is low, the addressed DAC’s input latch is
transparent. Data is latched when WR is high.
The MAX5100 LDAC feature allows simultaneous
updating of all four DACs. LDAC low latches the data in
the data registers to the DAC registers. If simultaneous
updating is not required, tie LDAC low to keep the DAC
latches transparent. If WR and LDAC are low simultane-
ously, avoid output glitches by ensuring that data is
valid before the two signals go low. When the device
powers up (i.e., VDD ramps up), all latches are internal-
ly preset with code 00 hex.
Applications Information
External Reference
The reference source resistance must be considerably
less than the reference input resistance. To keep within
1LSB error in an 8-bit system, RS must be less than
RREF / 256. Hence, maintain a value of RS <1k
to
ensure 8-bit accuracy. If VREF is DC only, bypass REF
to GND with a 0.1F capacitor. Values greater than this
improve noise rejection.
Power Sequencing
The voltage applied to REF should not exceed VDD at
any time. If proper power sequencing is not possible,
connect an external Schottky diode between REF and
VDD to ensure compliance with the absolute maximum
ratings.
Power-Supply Bypassing and
Ground Management
Digital or AC transient signals on GND can create noise
at the analog output. Return GND to the highest-quality
ground available. Bypass VDD with a 0.1F capacitor,
located as close to VDD and GND as possible.
Careful PC board ground layout minimizes crosstalk
between the DAC outputs and digital inputs.
