fO (Pin 1): Frequency Control Pin. Digital input that controls
the internal conversion clock rate. When fO is connected to
GND, the converter uses its internal oscillator running at
307.2kHz. The conversion clock may also be overridden by
driving the fO pin with an external clock in order to change
the output rate and the digital lter rejection null.
CA0, CA1 (Pins 2, 3): Chip Address Control Pins. These
pins are congured as a three-state (LOW, HIGH, Floating)
address control bits for the device’s I2C address.
SCL (Pin 4): Serial Clock Pin of the I2C Interface. The
LTC2487 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.
SDA (Pin 5): Bidirectional Serial Data Line of the I2C Inter-
face. In the transmitter mode (Read), the conversion result
is output through the SDA pin, while in the receiver mode
(Write), the device channel select and conguration bits
are input through the SDA pin. The pin is high impedance
during the data input mode and is an open drain output
(requires an appropriate pull-up device to VCC) during the
data output mode.
GND (Pin 6): Ground. Connect this pin to a common ground
plane through a low impedance connection.
COM (Pin 7): The Common Negative Input (IN–) for All
Single-Ended Multiplexer Congurations. The voltage
on CH0-CH3 and COM pins can have any value between
