PIN FUNCTIONS
V1 (Pin 1): First Monitor Input. This pin can be config-
ured as a single-ended input or the positive input for a
differential or remote diode temperature measurement (in
combination with V2). When configured for remote diode
temperature, this pin will source a current.
V2 (Pin 2): Second Monitor Input. This pin can be con-
figured as a single-ended input or the negative input for a
differential or remote diode temperature measurement (in
combination with V1). When configured for remote diode
temperature, this pin will have an internal termination,
while the measurement is active.
V3 (Pin 3): Third Monitor Input. This pin can be config-
ured as a single-ended input or the positive input for a
differential or remote diode temperature measurement (in
combination with V4). When configured for remote diode
temperature, this pin will source a current.
V4 (Pin 4): Fourth Monitor Input. This pin can be config-
ured as a single-ended input or the negative input for a
differential or remote diode temperature measurement (in
combination with V3). When configured for remote diode
temperature, this pin will have an internal termination,
while the measurement is active.
GND (Pin 5): Device Circuit Ground. Connect this pin to a
ground plane through a low impedance connection.
SDA (Pin 6): Serial Bus Data Input and Output. In the
transmitter mode (Read), the conversion result is output
through the SDA pin, while in the receiver mode (Write),
the device configuration bits are input through the SDA
pin. At data input mode, the pin is high impedance; while
at data output mode, it is an open-drain N-channel driver
andthereforeanexternalpull-upresistororcurrentsource
to VCC is needed.
SCL (Pin 7): Serial Bus Clock Input. The LTC2990 can
only act as a slave and the SCL pin only accepts external
serial clock. The LTC2990 does not implement clock
stretching.
ADR0 (Pin 8): Serial Bus Address Control Input. The ADR0
pin is an address control bit for the device I2C address.
ADR1 (Pin 9): Serial Bus Address Control Input. The
ADR1 pin is an address control bit for the device I2C
address. See Table 2.
VCC (Pin 10): Supply Voltage Input.
