PIN FUNCTIONS
GND (Pins 1, 4, 9): Ground. All GND pins must be con-
nected to a solid ground plane.
SDA (Pin 2): Bidirectional Serial Data Line of the I2C In-
terface. In transmitter mode (read), the conversion result
is output at the SDA pin, while in receiver mode (write),
the DIN word is input at the SDA pin to congure the ADC.
The pin is high impedance during the data input mode and
is an open drain output (requires an appropriate pull-up
device to VDD) during the data output mode.
SCL (Pin 3): Serial Clock Pin of the I2C Interface. The
LTC2305 can only act as a slave and the SCL pin only ac-
cepts an external serial clock. Data is shifted into the SDA
pin on the rising edges of the SCL clock and output through
the SDA pin on the falling edges of the SCL clock.
CH0-CH1 (Pins 5, 6): Channel 0 and Channel 1 Analog
Inputs. CH0 and CH1 can be congured as single-ended
or differential input channels. See the Analog Input Multi-
plexer section.
VREF (Pin 7): 2.5V Reference Output. Bypass to GND with
a minimum 2.2μF ceramic capacitor. The internal refer-
ence may be overdriven by an external 2.5V reference at
this pin.
REFCOMP (Pin 8): Reference Buffer Output. Bypass to
GND with 10μF and 0.1μF ceramic capacitors in parallel.
Nominal output voltage is 4.096V. The internal reference
buffer driving this pin is disabled by grounding VREF, al-
lowing REFCOMP to be overdriven by an external source
(see Figure 5c).
VDD (Pin 10): 5V Analog Supply. The range of VDD is 4.75V
to 5.25V. Bypass VDD to GND with 10μF and 0.1μF ceramic
capacitors in parallel.
AD1 (Pin 11): Chip Address Control Pin. This pin is con-
gured as a three-state (LOW, HIGH, oating) address
control bit for the device I2C address. See Table 2 for
address selection.
AD0 (Pin 12): Chip Address Control Pin. This pin is con-
gured as a three-state (LOW, HIGH, oating) address
control bit for the device I2C address. See Table 2 for
address selection.
GND (Pin 13 – DFN Package Only): Exposed Pad Ground.
Must be soldered directly to ground plane.
