External Reference
The MAX7651/MAX7652 require external reference volt-
ages at V
REF+
and V
REF-
. A single reference voltage
can be used at V
REF+,
when V
REF-
is connected to
AGND. The positive reference voltages must be no
greater than the analog supply voltage AV
DD
and
capable of supplying 30μA. Bypass each reference
voltage to AGND with a 0.1μF capacitor in parallel with
a 10μF low ESR capacitor.
PWM Digital-to-Analog Converters (DACs)
The MAX7651/MAX7652 provide two pulse-width mod-
ulated (PWM) DACs for applications that do not require
high conversion accuracy. Figure 8 shows the pulse-
width-modulator block diagram. The clock signal is
divided by 2 (x + 1), where x is the content of the
Pulse-Width Prescaler (PWPS) SFR register. This
reduced frequency signal is used to drive a modulo-
255 counter. When the counter value exceeds the
value stored in SFRs PWDA (Output A) or PWDB
