Description
No Connection. Do not connect anything to this pin.
Digital I/O. Serial bus bidirectional data. Push-pull output.
Digital Input. Serial bus clock.
This pin is a logic output. The overtemperature indicator (OTI) is set if the result of a conversion on Channel 0
(temperature sensor) is greater than an 8-bit word in the T
serial read operation. Open-drain output.
Reference Input. An external 2.5 V reference can be connected to the AD7417 at this pin. To enable the on-chip
reference, the REF
reference shuts down.
Ground reference for track-and-hold, comparator and capacitor DAC, and digital circuitry.
Analog Input Channels. The AD7417 has four analog input channels. The input channels are single-ended with
respect to GND. The input channels can convert voltage signals in the range of 0 V to VREF. A channel is selected by
writing to the configuration register of the AD7417.
Digital Input. This is the highest programmable bit of the serial bus address.
Digital Input. This is the middle programmable bit of the serial bus address.
Digital Input. This is the lowest programmable bit of the serial bus address.
Positive Supply Voltage, 2.7 V to 5.5 V.
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 the
IN
pin should be tied to GND. If an external reference is connected to the AD7417, the internal
