APPLICATIONS INFORMATION
Power On Reset
At power up, all inputs are reset to 0 V if WR = 1. For WR = 0,
the addressed DAC will receive input data.
Power Supply
The MP7226 can operate with either a single or dual power
supply. Improved zero-code settling error can be obtained by
using dual power supplies. The dual power supply specifica-
tions are a positive supply (VDD) range of +10.5V to +16.5V, and
a –5V supply (VSS) . The single power supply specifications are
a positive supply (VDD) range of +10.5V to +16.5V, or range of
+4.75V to 5.5V . The specified reference voltage (VREF) range
under these conditions is from +2V to VDD –4V. For those appli-
cations requiring +10V at the output (VREF = +10V), VDD must
be +14V minimum to meet data sheet limits . 8-bit performance
is guaranteed for single supply operation (VSS = 0V); however,
zero code output sink capability is improved with VSS = –5V. For
adequate DAC and Buffer operation, VREF must always be be-
low VDD by at least 3.5V.
Power Supply Decoupling
The Power Supplies used with the MP7226 should be well
regulated and filtered. Local power supply decoupling consist-
ing of a 10
µF tantalum capacitor in parallel with a 0.01µF ce-
ramic is recommended. The decoupling capacitors should be
connected between the VDD and AGND, and between VSS and
AGND if VSS = –5V.
Unipolar Output Operation
In this configuration, the reference voltage is the same polar-
ity as the output voltage. Since the reference voltage must al-
ways be positive with respect to GND, the output can only be 0 or
positive.
Table 2. shows the code relationship for the part in unipolar
operation
