... A0, A1, and A2 being the address of the device. Application Considerations The DS1803 is offered in three standard resistor values which include the 10k , 50k , and 100k . The resolution of the potentiometer is defined as R potentiometer. The DS1803 is designed to operate using power supplies over the industrial (- +85 C) temperature range ...

... STOP condition or with a repeated START condition. Since a repeated START condition is also the beginning of the next serial transfer, the bus will not be released. The DS1803 may operate in the following two modes: 1. Slave receiver mode: Serial data and clock are received through SDA and SCL. After each byte is received, an acknowledge bit is transmitted ...

... A control byte is the first byte received following the START condition from the master device. The control byte consist of a four bit control code; for the DS1803, this is set as 0101 binary for read/write operations. The next three bits of the control byte are the device select bits (A2, A1, A0). They are used by the master device to select which of eight devices are to be accessed ...

... DS1803. Once the control byte has been issued and the master receives the acknowledgment from the DS1803, the command byte is transmitted to the DS1803. As mentioned above, there exist three write operations that can be used with the DS1803. The binary value of each write command is shown in Figure 5 and also in the Table 1. ...
