analog input mode(continued)
differential input
In this mode, the first differential input is applied to the AIN pin and the second differential input is applied to the
common point where REFTS and REFBS are tied together. The common mode of the input should be set to
AVDD/2 as shown in Figure 11. The maximum magnitude of the differential input signal should be equal to VREF.

digital input mode
D 3-State Output: The digital outputs can be set to high-impedance state by applying a LO logic to the OE
pin.
D Power Down: The whole device will power down by applying a HI logic to the STBY pin. The ADC will wake
up in 400 ns after the pin STBY is reset.
TLC876 mode
The THS1030 is pin compatible with the TI TLC876 and thus enables users of TLC876 to upgrade to higher
speed by dropping the THS1030 into their sockets. The external reference input for the TLC876 is shown on
the reference pins of the THS1030.
