DESCRIPTION
aleA
185
I
application layers interface Address Latch Enable (only for
multiplexed micro-processor).
VIP
118
I
IF analog OOB input signal. Positive input to the A/D converter. This
pin is DC biased to half-supply through an internal resistor divider (2
x 10k
resistors). In order to remain in the range of the ADC, the
voltage difference between pins VIP and VIM should be between
-0.5 and 0.5 volts.
VIM
117
I
IF analog OOB input signal. Negative input to the A/D converter.
This pin is DC biased to half-supply through an internal resistor
divider (2 x 10k
resistors). In order to remain in the range of the
ADC, the voltage difference between pins VIP and VIM should be
between -0.5 and 0.5 volts.
CMCAP
111
I
This pin is connected to a tap point on an internal resistor divider
used to create CMO and CMI. An external capacitor of value .1
f
should be connected between this point and ground to provide good
power supply rejection from the positive supply at higher
frequencies.
RBIAS
108
I
An external resistor of value 3.3k
should be connected between
this pin and ground to provide good accurate bias currents for the
analog circuits on the ADC.
VREF
114
O
This is the output of an on-chip resistor divider. An external
capacitor of value .1
f should be connected between this point and
ground to provide good power supply rejection from the positive
supply at higher frequencies. Reference voltages VREFP and
VREFM are derived from the voltage on VREF.
VREFP
113
O
This is a positive voltage reference for the A/D converter. It is
derived from the voltage on pin VREF through an on-chip fully-
differential amplifier. The voltage on this pin is nominally equal to
CMO + 0.25 volts.
VREFM
112
O
This is the negative voltage reference for the A/D converter. It is
derived from the voltage on pin VREF through an on-chip fully-
differential amplifier. The voltage on this pin is nominally equal to
CMO - 0.25 volts.
CMO
110
O
This pin provides the common-mode out voltage for the analog
circuits on the ADC. It is the buffered version of a voltage derived
from an on-chip resistor devider, and has a nominal value of 0.5 x
VD3.
CMI
109
O
This pin provides the common-mode in voltage for the analog
circuits on the ADC. It is the buffered version of a voltage derived
from an on-chip resistor devider, and has a nominal value of 0.75 x
VD3.
VD1
107
I
Power supply input for the digital switching circuitry (3.3V typ).
VS1
106
I
Ground return for the digital switching circuitry.
VD2
120
I
Power supply input for the analog clock drivers (3.3V typ).
VS2
119
I
Ground return for the analog clock drivers.
VD3
115
I
Power supply input for the analog circuits (3.3V typ).
VS3
116
I
Ground return for analog circuits.
VD4
121
I
Power supply input connected to an n-well guard ring that surrounds
the ADC (3.3V typ).
VS4
105
I
Ground for a p+ guard ring that surrounds the ADC.
