Figure 26. AC-coupled differential input
Figure 26 represents the biasing of a differential input signal in an AC-coupled differential
input configuration. Both inputs VIN and VINB are centered around the common mode
voltage, which can be left internal, or fixed externally.
Figure 27. DC-coupled 2 Vpp differential analog input
Figure 27 shows a DC-coupled configuration with forced VREFP and INCM to the 1V DC
analog input while VREFM is connected to ground; the differential amplitude obtained is
2Vpp.

Clock input
The quality of your TSA1203 converter is very dependent on your clock input accuracy, in
terms of aperture jitter; the use of a low jitter crystal controlled oscillator is recommended.
Further points to consider in your implementation are:
●
The duty cycle must be between 45% and 55%.
●
The clock power supplies must be independent from the ADC output supplies to avoid
digital noise modulation on the output.
●
When powered-on, the circuit needs several clock periods to reach its normal operating
conditions. Therefore, it is recommended to keep the circuit clocked to avoid random
states before applying the supply voltages.
