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.
