DESCRIPTION

The THS1207 is a CMOS, low-power, 12-bit, 6 MSPS

analog-to-digital converter (ADC). The speed,

resolution, bandwidth, and single-supply operation are

suited for applications in radar, imaging, high-speed

acquisition, and communications. A multistage

pipelined architecture with output error correction logic

provides for no missing codes over the full operating

temperature range. Internal control registers are used

to program the ADC into the desired mode. The

THS1207 consists of four analog inputs, which are

sampled simultaneously. These inputs can be selected

individually and configured to single-ended or

differential-inputs. Internal reference voltages for the

ADC (1.5 V and 3.5 V) are provided. An external

reference can also be chosen to suit the dc accuracy

and temperature drift requirements of the application.

The THS1207C is characterized for operation from 0°C

to 70°C, the THS1207I is characterized for operation

from –40°C to 85°C.
