description

The THS0842 is a dual 8-bit 40 MSPS high-speed A/D converter. It alternately converts each analog input signal

into 8-bit binary-coded digital words up to a maximum sampling rate of 40 MSPS with an 80 MHz clock. All digital

inputs and outputs are 3.3 V TTL/CMOS-compatible.

Thanks to an innovative single-pipeline architecture implemented in a CMOS process and the 3.3 V supply, the

device consumes very little power. In order to provide maximum flexibility, both bottom and top voltage

references can be set from user supplied voltages. Alternately, if no external references are available, on-chip

references can be used which are also made available externally. The full-scale range is 1 Vpp, depending on

the analog supply voltage. If external references are available, the internal references can be powered down

independently from the rest of the chip, resulting in an even greater power saving.

The device is specifically suited for the baseband sampling of wireless local loop (WLL) communication, cable

modems, set top boxes (STBs), and test instruments.
