TYPICAL PERFORMANCE CHARACTERISTICS
PIN FUNCTIONS
ADIN: ADC Input. The onboard ADC measures voltage
range between 0V and 2.048V. Tie to GND if unused.
ADR1, ADR0: I
ADR1 and ADR0 to V
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
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
is internally clamped to 6V (5.5V minimum).
SDA (LTC4151 Only): I
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
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, data, and SDAO
acknowledge bits. This pin is driven by an open-collector

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.
