Description
Analog Input. Single-ended analog input channel. Input range is 0 V to 2.25 V or 0 V to V
DD
.
Analog Input. Single-ended analog input channel. Input range is 0 V to 2.25 V or 0 V to V
DD
.
No Connection to This Pin.
SPI—Active Low Control Input. This is the frame synchronization signal for the input data. When CS goes low, it
enables the input register and data is transferred in on the rising edges and out on the falling edges of the
subsequent serial clocks. It is recommended that this pin be tied high to V
DD
when operating the serial interface in I
2
C
mode.
Ground Reference Point for All Circuitry on the Part. Analog and digital ground.
Positive Supply Voltage, 2.7 V to 5.5 V. The supply should be decoupled to ground.
D+. Positive connection to external temperature sensor. AIN1. Analog Input. Single-ended analog input channel.
Input range is 0 V to 2.25 V or 0 V to 5 V.
D. Negative connection to external temperature sensor. AIN2. Analog Input. Single-ended analog input channel.
Input range is 0 V to 2.25 V or 0 V to 5 V.
Analog Input. Single-ended analog input channel. Input range is 0 V to 2.25 V or 0 V to V
DD
.
Over Limit Interrupt. The output polarity of this pin can be set to give an active low or active high interrupt when
temperature, V
DD
, or AIN limits are exceeded. Default is active low. Open-drain output, needs a pull-up resistor.
SPI. Serial Data Output. Logic output. Data is clocked out of any register at this pin. Data is clocked out on the falling
edge of SCLK. Open-drain output, needs a pull-up resistor.
ADD. I
2
C serial bus address selection pin. Logic input. A low on this pin gives the Address 1001 000. Leaving it floating
gives the address 1001 010, and setting it high gives the Address 1001 011. The I
2
C address set up by the ADD pin is
not latched by the device until after this address has been sent twice. On the eighth SCL cycle of the second valid
communication, the serial bus address is latched in. Any subsequent changes on this pin will have no effect on the I
2
C
serial bus address.
SDA. I
2
C serial data input. I
2
C serial data to be loaded into the part’s registers is provided on this input. An open-drain
configuration, it needs a pull-up resistor.
DIN. SPI serial data input. Serial data to be loaded into the part’s registers is provided on this input. Data is clocked
into a register on the rising edge of SCLK. Open-drain configuration, needs a pull-up resistor.
Serial Clock Input. This is the clock input for the serial port. The serial clock is used to clock data out of any register of
the ADT7411 and also to clock data into any register that can be written to. An open-drain configuration, it needs a
pull-up resistor.
Analog Input. Single-ended analog input channel. Input range is 0 V to 2.25 V or 0 V to V
