LTC1669IMS8-PBF

10-Bit Rail-to-Rail Micropower DAC with I2C Interface

Linear Technology 

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 VCC.

AD1 (Pin 2): Slave Address Select Bit 1. Tie this pin to

either VCC or GND to modify the corresponding bit of the

LTC1669’s slave address.

AD2 (Pin 3): Slave Address Select Bit 2. Tie this pin to

either VCC or GND to modify the corresponding bit of the

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 VCC.

VCC (Pin 5, Pin 4 on SOT-23): Power Supply. 2.7V ≤ VCC

≤ 5.5V. Also used as the reference voltage input when the

part is programmed to use VCC as the reference.

AD0 (Pin 6): Slave Address Select Bit 0. Tie this pin to

either VCC or GND to modify the corresponding bit of the

LTC1669’s slave address.

GND (Pin 7, Pin 2 on SOT-23): System Ground.

VOUT (Pin 8, Pin 3 on SOT-23): Voltage Output. Buffered

rail-to-rail DAC output.
