REFERENCE SET TO
INTERNAL BANDGAP
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
LTC1663’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
LTC1663’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
LTC1663’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.
Differential Nonlinearity (DNL): The difference between
the measured change and the ideal 1LSB change for any
two adjacent codes. The DNL error between any two codes
is calculated as follows:
DNL = (ΔVOUT – LSB)/LSB
Where ΔVOUT is the measured voltage difference between
two adjacent codes.
Digital Feedthrough: The glitch that appears at the ana-
log output caused by AC coupling from the digital inputs
when they change state. The area of the glitch is specied
in (nV)(sec).
Full-Scale Error (FSE): The deviation of the actual full-scale
voltage from ideal. FSE includes the effects of offset and
gain errors (see Applications Information).
