CURRENT SETTING RESISTOR (Rref) AND
OUTPUT LOAD RESISTOR (RL) (external components)
Full-scale output amplitude (VFS) of each D/A converter is ;
VFS = (VG / Rref) x 16 x RL (VP-P).
where VG = 1.28 V, Rref = 768 Ω, RL = 75 Ω and VDD = 5.0V.
The full-scale output of about 2.0 VP-P is available by setting RL and
Rref to 75 Ω and 768 Ω, respectively.
An output impedance of the analog output terminal is almost the
same as the load resistor (RL).
NOTES TO THE OPERATION
MITSUBISHI ICs (AV COMMON)
M65530FP
TRIPLE 10-BIT VIDEO D-A CONVERTER
1. Both a ground and a supply planes in a PCB should be as wide
as possible for reducing a parasitic inductance and resistance.
Especially, for the better performance, the analog plane needs to
be much wider.
2. A tantalum or electrolytic capacitor of 10µF or more and a
ceramic capacitor of 0.01µF are tied together, which are
connected between a digital supply and ground, also between a
analog supply and ground.
These capacitors should be placed as close as possible to the
IC.
They work as bypass capacitors for preventing a degradation in
the performance by a supply voltage
fluctuation caused by digital signals including a clock and digital
inputs and so on.
3. The analog output should be isolated as much as possible from a
clock and digital inputs, thus minimizing decoupling and
interactive noise.
