pin FuncTions
ADIN: ADC Input. The onboard ADC measures voltage 
range between 0V and 2.048V. Tie to GND if unused.
ADR1, ADR0: I
2
C Device Address Inputs. Connecting
ADR1 and ADR0 to V
IN
, GND or leaving the pins open
configures one of nine possible addresses. See Table 1
in the Applications Information section for details.
Exposed Pad (DD Package Only): Exposed pad may be 
left open or connected to device ground (GND).
GND: Device Ground. 
SCL: I
2
C Bus Clock Input. Data is shifted in and out at
the SDA pin on rising edges of SCL. This pin is driven
by an open-collector output from a master controller. An
external pull-up resistor or current source is required and
can be placed between SCL and V
IN
. The voltage at SCL
is internally clamped to 6V (5.5V minimum).
SDA (LTC4151 Only): I
2
C Bus Data Input/Output. Used
for shifting in address, command or data bits and sending
out data. An external pull-up resistor or current source
is required and can be placed between SDA and V
IN
.
The voltage at SDA is internally clamped to 6V (5.5V
minimum).
SDAI (LTC4151-1/LTC4151-2 Only): I
2
C Bus Data Input.
Used for shifting in address, command, data, and SDAO
acknowledge bits. This pin is driven by an open-collector
output from a master controller. An external pull-up resistor
or current source is required and can be placed between
SDAI and V
IN
. If the master separates SDAI and SDAO,
data read at SDAO needs to be echoed back to SDAI for
proper I
2
C communication. The voltage at SDAI is internally
clamped to 6V (5.5V minimum).
SDAO (LTC4151-2 Only): Serial Bus Data Output. Open-
drain output used for sending data back to the master
controller or acknowledging a write operation. Normally
tied to SDAI to form the SDA line. An external pull-up
resistor or current source is required.
SDAO (LTC4151-1 Only): Inverted Serial Bus Data Out-
put. Open-drain output used for sending data back to the
master controller or acknowledging a write operation. Data
is inverted for convenience of opto-isolation. An external
pull-up resistor or current source is required.
SENSE
+
: Kelvin Sense of the V
IN
 Pin. See Figure 10 for
recommended Kelvin connection.
SENSE

:  High  Side  Current  Sense  Input.  Connect  an 
external sense resistor between SENSE
+
 and SENSE

.
The differential voltage between SENSE
+
 and SENSE

 is
monitored by the onboard ADC with a full-scale sense
voltage of 81.92mV.
