LTC1669
PIN FUNCTIONS
SDA (Pin 1, Pin 1 on SOT-23): Serial Data Bidirectional
Pin. Data is shifted into the SDA pin and acknowledged
by the SDA pin. High impedance pin while data is shifted
in. Open-drain N-channel output during acknowledgment.
Requires a pull-up resistor or current source to V
AD1 (Pin 2): Slave Address Select Bit 1. Tie this pin to
either V
LTC1669’s slave address.
AD2 (Pin 3): Slave Address Select Bit 2. Tie this pin to
either V
LTC1669’s slave address.

SCL (Pin 4, Pin 5 on SOT-23): Serial Clock Input Pin.
Data is shifted into the SDA pin at the rising edges of the
clock. This high impedance pin requires a pull-up resistor
or current source to V
V
≤ 5.5V. Also used as the reference voltage input when the
part is programmed to use V
AD0 (Pin 6): Slave Address Select Bit 0. Tie this pin to
either V
