BRS
Generates approximately +0.4V when shorted
with V
RB
.
26
V
REF
Clamp Reference Voltage Input. Clamps so
that the reference voltage and the input signal
during clamp interval are equal.
27
CCP
Integrates the clamp control voltage. The
relationship between the changes in CCP
voltage and in V
IN
voltage is positive phase.
28, 31
DV
SS
Digital Ground.
29
CLE
The clamp function is enabled when
CLE = Low.
The clamp function is set to off and the
converter functions as a normal A/D converter
when CLE = High.
The clamp pulse can be measured by
connecting
CLE
to
several-hundred-ohm resistor.

30
OE
Data is output when OE = Low. Pins D0 to D7
are at high impedance when OE = High.
32
NC
No Connect pin.
