SERIAL PROGRAMMING INTERFACE
The ADS5510 has internal registers for the programming of some of the modes described in the previous
sections. The registers should be reset after power-up by applying a 2 µs (minimum) high pulse on RESET (pin
35); this also resets the entire ADC and sets the data outputs to low. This pin has a 200-kΩ internal pullup
resistor to AVDD. The programming is done through a three-wire interface. The timing diagram and serial
register setting in the Serial Programing Interface section describe the programming of this register.
Table 2 shows the different modes and the bit values to be written to the register to enable them.
Note that some of these modes may modify the standard operation of the device and possibly vary the
performance with respect to the typical data shown in this data sheet.
Applying a RESET signal is must to set the internal registers to their default states for normal operation. If the
hardware RESET function is not used in the system, the RESET pin must be tied to ground and it is necessary
to write the default values to the internal registers through the serial programming interface. The registers must
be written in the following order.
Write 9000h (Address 9, Data 000)
Write A000h (Address A, Data 000)
Write B000h (Address B, Data 000)
Write C000h (Address C, Data 000)
Write D000h (Address D, Data 000)
Write E000h (Address E, Data 804)
Write 0000h (Address 0, Data 000)
Write 1000h (Address 1, Data 000)
Write F000h (Address F, Data 000)
NOTE:
This procedure is only required if a RESET pulse is not provided to the device.
