PARAMETER MEASUREMENT INFORMATION
sample timing
The THS1401/3/8 core is based on a pipeline architecture with a latency of 9.5 samples. The conversion results
appear on the digital output 9.5 clock cycles after the input signal was sampled.

Figure 1. Sample Timing
The parallel interface of the THS1401/3/8 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 offset 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.
