Operation
How to select the output resistance:
- The HI1177 is a D/A converter of the current output type.
To obtain the output voltage connect the resistance to IO
pin (Y0, C0). For specifications we have:
- Calculate the output resistance value from the relation
of V
FS
= I
FS
X R. Also, 16 times resistance of the output
resistance is connected to reference current pin I
REF
. In
some cases, however, this turns out to be a value that
does not actually exist. In such a case a value close to it
can be used as a substitute. Here please note that V
FS
becomes V
FS
= V
REF
X 16R/R’. R is the resistance
connected to IO while R’ is connected to I
REF
. Increas-
ing the resistance value can curb power consumption.
On the other hand glitch energy and data settling time
will inversely increase. Set the most suitable value
according to the desired application.
Phase relation between data and clock:
- To obtain the expected performance as a D/A converter, it
is necessary to set properly the phase relation between
data and clock applied from the exterior. Be sure to
satisfy the provisions of the set up time (t
S
) and hold time
(t
H
) as stipulated in the Electrical Characteristics.
V
DD
, V
SS
:
- To reduce noise effects separate analog and digital
systems in the device periphery. For V
DD
pins, both
digital and analog, bypass respective GNDs by using a
ceramic capacitor of about 0.1
μ
F, as close as possible
to the pin.
