Analog
input
I
1
thru I
6
Analog inputs for the six channels. One of the 6 is selected by a specific
bit pattern on A
0
to A
2
.

A
1
A
2
Input for selecting an analog input channel. Either GND, one of
channels I
1
to I
6
or V
REF
is selected by a specific bit pattern on the 3
inputs.
RAMP START A/D conversion start signal input. RAMP START (1

RAMP
STOP
signal
output
RAMP STOP
Indicates that C
H
is charged over comparator reference voltage V
BE2
.
RAMP STOP (0
→
1) A/D conversion end signal (C
H
discharged to
comparator reference voltage). RAMP STOP (0
→
1)
4
Ramp
capacitor
pin
C
H
Pin for externally connecting the ramp capacitor. The value of C
H
in
conjunction with V
REF
and R
REF
establishes the ramp time.
8
Reference
voltage
supply pin
V
REF
Reference voltage supply pin.
This is the reference voltage source for determining the discharge
current and the analog reference voltage for full-scale factor correction.
When the channel selection input is set 111, this pin is selected for
channel conversion. The full-scale factor is corrected using the
conversion results.
The voltage at this pin must be set to (GND + 2 V) to (V
CC
– 2 V) and
5.25 V or less.
6
Reference
resistance
pin
R
REF
Pin for external reference resistance for setting the discharge current.
The external resistance is connected between the power source pin
(V
CC
) and the reference resistance pin (R
REF
). The discharge current is,
then, I
R
= (V
CC
– V
REF
)/R
REF
.
14
Power
supply
V
CC
Power supply pin
5
Ground
GND
Ground pin
This pin is grounded. When the channel selection input is set to 000,
this terminal is selected for channel conversion. The zero offset is
corrected using the conversion results.
