7.3.7.2.11 Time Stamp

When configured through the TIME_STAMP_EN register setting (register 0x050, bit 5), the SYNC~ differential input (pins 22 and 23) can be used as a time-stamp input. The time-stamp feature enables the user to capture the timing of an external trigger event relative to the sampled signal. When enabled, the LSB of the 12-bit ADC digital output captures the trigger information. In effect, the 12-bit converter becomes an 11-bit converter and the LSB acts as a 1-bit converter with the same latency as the 11-bit converter. The trigger must be applied to the differential SYNC~/TMST inputs. The trigger can be asynchronous to the ADC sampling clock and is sampled at approximately the same time as the analog input.
