PARAMETER MEASUREMENT INFORMATION
The parallel interface of the THS14F01/3 ADC features 3-state buffers making it possible to directly connect
it to a data bus. The output buffers are enabled by driving the OE input low.
Besides the sample results, it is also possible to read back the values of the control register, the PGA register,
and the control register. Which register is read is determined by the address inputs A[1,0]. The ADC results are
available at address 0.
The timing of the control signals is described in the following sections.
The FIFO can be disabled by setting FC to 0 (FIFO reset, default at power on). This makes it possible to access
the device synchronously.
In this case the data is updated on every clock cycle.
