pin FuncTions ADIN:
ADC Input. The onboard ADC measures voltage output from a master controller. An external pull-up resistor range between 0V and 2.048V. Tie to GND if unused. or current source is required and can be placed between
ADR1, ADR0:
I2C Device Address Inputs. Connecting SDAI and VIN. If the master separates SDAI and SDAO, ADR1 and ADR0 to V data read at SDAO needs to be echoed back to SDAI for IN, GND or leaving the pins open configures one of nine possible addresses. See Table 1 proper I2C communication. The voltage at SDAI is internally in the Applications Information section for details. clamped to 6V (5.5V minimum).

SDAO (LTC4151-2 Only):
Serial Bus Data Output. Open- left open or connected to device ground (GND). drain output used for sending data back to the master controller or acknowledging a write operation. Normally
GND:
Device Ground. tied to SDAI to form the SDA line. An external pull-up
SCL:
I2C Bus Clock Input. Data is shifted in and out at resistor or current source is required. the SDA pin on rising edges of SCL. This pin is driven

Inverted Serial Bus Data Out- by an open-collector output from a master controller. An put. Open-drain output used for sending data back to the external pull-up resistor or current source is required and master controller or acknowledging a write operation. Data can be placed between SCL and VIN. The voltage at SCL is inverted for convenience of opto-isolation. An external is internally clamped to 6V (5.5V minimum). pull-up resistor or current source is required.

Kelvin Sense of the VIN Pin. See Figure 10 for for shifting in address, command or data bits and sending recommended Kelvin connection. out data. An external pull-up resistor or current source is required and can be placed between SDA and V
SENSE–:
High Side Current Sense Input. Connect an IN. The voltage at SDA is internally clamped to 6V (5.5V external sense resistor between SENSE+ and SENSE–. minimum). The differential voltage between SENSE+ and SENSE– is monitored by the onboard ADC with a full-scale sense
SDAI (LTC4151-1/LTC4151-2 Only):
I2C Bus Data Input. voltage of 81.92mV. Used for shifting in address, command, data, and SDAO acknowledge bits.
