Digital I/O. Serial bus bidirectional data. Push-pull output.  
Digital Input. Serial bus clock.  
SCL  
OTI  
This is a logic output. The OTI is set if the result of a conversion on Channel 0 (temperature sensor) is  
greater that an 8-bit word in the OTR. The signal is reset at the end of a serial read operation. Open-  
drain output.

A2  
Ground reference for track-and-hold, comparator and capacitor DAC, and digital circuitry.  
Digital Input. The highest programmable bit of the serial bus address.  
Digital Input. The middle programmable bit of the serial bus address.  
Digital Input. The lowest programmable bit of the serial bus address.  
Positive Supply Voltage, 2.7 V to 5.5 V.

GND  
AIN  
Ground reference for track-and-hold, comparator and capacitor DAC, and digital circuitry.  
Analog Input Channel. The input channel is single-ended with respect to GND. The input channel can  
convert voltage signals in the range 0 V to VREF. The analog input channel is selected by writing to the  
configuration register of the AD7418 and choosing Channel 4. (See Control Byte section.)  
6
REFIN  
Reference Input. An external 2.5 V reference can be connected to the AD7418 at this pin. To enable the  
on-chip reference, the REFIN pin should be tied to GND. If an external reference is connected to the  
AD7418, the internal reference will shut down.

8
VDD  
Positive Supply Voltage, 2.7 V to 5.5 V.  
CONVST  
Logic Input Signal. Convert start signal. The rising edge of this signal fully powers up the part. The  
power-up time for the part is 4 µs. If the CONVST pulse is greater than 4 µs, the falling edge of  
CONVST places the track-and-hold mode into hold mode and initiates a conversion. If the pulse is less  
than 4 µs, an internal timer ensures that the track-and-hold does not go into hold and conversion is not  
initiated until the power-up time has elapsed. The track-and-hold goes into track mode again at the end  
of conversion. (See Operating Mode section.)
