Pin No. Mnemonic Function
1 2 3 4 5 6 VDD GND VIN SCLK SDATA CS Power Supply Input. The VDD range for the AD7476/AD7477/AD7478 is from 2.35 V t0 5.25 V. Analog Ground. Ground reference point for all circuitry on the AD7476/AD7477/AD7478. All analog input signals should be referred to this GND voltage. Analog Input. Single-ended analog input channel. The input range is o V to VDD. Serial Clock. Logic input. SCLK provides the serial clock for accessing data from the part. This clock input is also used as the clock source for the AD7476/AD7477/AD7478's conversion process. Data Out. Logic output. The conversion result from the AD7476/AD7477/AD7478 is provided on this output as a serial data stream. The bits are clocked out on the falling edge of the SCLK input. The data stream from the AD7476 consists of four leading zeros followed by the 12 bits of conversion data, which is provided MSB first; the data stream from the AD7477 consists of four leading zeros followed by the 10 bits of conversion data, followed by two trailing zeros, which is also provided MSB first; the data stream from the AD7478 consists of four leading zeros followed by the eight bits of conversion data, followed by four trailing zeros, which is provided MSB first. Chip Select. Active low logic input. This input provides the dual function ofinitiating conversions on the AD7476/AD7477/AD7478 and framing the serial data transfer.

The master device can check the alarm flag status of all DS18820Xs on the bus by issuing an Alarm Search [ECh] command. Any DS18820Xs with a set alarm flag will respond to the command, so the master can determine exactly which DS18820Xs have experienced an alarm condition. If an alarm condition exists and the TH or TL settings have changed, another temperature conversion should be done to validate the alarm condition.
