THS1030
2.7 V – 5.5 V, 10-BIT, 30 MSPS
CMOS ANALOG-TO-DIGITAL CONVERTER
SLAS243A – NOVEMBER 1999 – REVISED JANUARY 2000
PRINCIPLES OF OPERATION
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. Floating the MODE pin effectively puts the THS1030 into
876 mode using the external ADC reference. The REFSENSE pin will be connected to DV_DD by the TLC876
socket. In the TLC876/AD876 mode, the pipeline latency will be switched to 3.5 cycles to match TLC876/AD876
specifications.
