Output Data Format
Two output data formats are supported
– 2s complement and straight binary. They can be selected using the
serial interface register bit
<DATA FORMAT> or controlling the SEN pin in parallel configuration mode.
In the event of an input voltage overdrive, the digital outputs go to the appropriate full scale level. For a positive
overdrive, the output code is 0x7FF in offset binary output format, and 0x3FF in 2s complement output format.
For a negative input overdrive, the output code is 0x000 in offset binary output format and 0x400 in 2s
complement output format.
Multiplexed Output Mode
This mode is available only with CMOS interface. In this mode, the digital outputs of both the channels are
multiplexed and output on a single bus (DB0-DB13 pins), as per the timing diagram shown in Figure 99. The
channel A output pins (DA0-DA10
) are three-stated. Since the output data rate on the DB bus is
effectively doubled, this mode is recommended only for low sampling frequencies (
< 65 MSPS).
This mode can be enabled using register bits
<POWER DOWN MODES> or using the parallel pins CTRL1 -3.

Low Latency Mode
The default latency of ADS62P4X is 14 clock cycles. For applications, which cannot tolerate large latency,
ADS62P4X includes a special mode with 10 clock cycles latency. In the low latency condition, the Digital
Processing block is bypassed and its features (offset correction, fine gain, decimation filters) are not available.
