confi gures one of nine possible addresses. See Table 1
in the Applications Information section for details.
ADIN: ADC Input. The onboard ADC measures voltage
range between 0V and 2.048V. Tie to GND if unused.
SCL: I
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

The voltage at SDA is internally clamped to 6V (5.5V
minimum).
SDAI (LTC4151-1/LTC4151-2 Only): I
Used for shifting in address, command or data 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
age 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.
SHDN (LTC4151 Only): Shutdown Input. Internally pulled
up to 6.3V. Pull this pin below 1V to force the LTC4151 into
shutdown mode. Leave this pin open if unused.
