Figure 19. Power vs. Throughput Rate  
AD7817 SERIAL INTERFACE  
Figure 18 shows how the Automatic Power-Down is imple-  
mented to achieve the optimum power performance from the  
AD7816, AD7817 and AD7818. The devices are operated in  
Mode 2 and the duration of CONVST pulse is set to be equal to  
the power-up time (2 µs). As the throughput rate of the device is  
reduced the device remains in its power-down state longer, and  
the average power consumption over time drops accordingly.  
The serial interface on the AD7817 is a five-wire interface with  
read and write capabilities, with data being read from the output  
register via the DOUT line and data being written to the control  
register via the DIN line. The part operates in a slave mode and  
requires an externally applied serial clock to the SCLK input to  
access data from the data register or write to the control byte.  
The RD/WR line is used to determine whether data is being  
written to or read from the AD7817. When data is being written  
to the AD7817, the RD/WR line is set logic low and when data  
is being read from the part the line is set logic high—see Figure  
20. The serial interface on the AD7817 is designed to allow the  
part to be interfaced to systems that provide a serial clock that is  
synchronized to the serial data, such as the 80C51, 87C51,  
68HC11, 68HC05 and PIC16Cxx microcontrollers.  
For example, if the AD7817 is operated in a continuous sam-  
pling mode with a throughput rate of 10 kSPS, the power con-  
sumption is calculated as follows. The power dissipation during  
normal operation is 6 mW, VDD = 3 V. If the power up time is  
2 µs and the conversion time is 9 µs, the AD7817 can be said to  
dissipate 6 mW typically for 11 µs (worst case) during each  
conversion cycle. If the throughput rate is 10 kSPS, the cycle  
time is 100 µs and the power dissipated during each cycle is  
(11/100) × (6 mW) = 600 µW typ.
