描述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 THS1207Iis characterized for operation from –40°C to 85°C.特性Simultaneous Sampling of 4 Single-Ended Signals or 2 Differential Signals or Combination of Both Signal-to-Noise and Distortion Ratio: 68 dB at fI = 2 MHz Differential Nonlinearity Error: ±1 LSB Integral Nonlinearity Error: ±1.5 LSB Auto-Scan Mode for 2, 3, or 4 Inputs 3-V or 5-V Digital Interface Compatible Low Power: 216 mW Max at 5 V Power Down: 1 mW Max 5-V Analog Single Supply Operation Internal Voltage References ...50 PPM/°C and ±5% Accuracy Glueless DSP Interface Parallel µC/DSP Interface APPLICATIONS Radar Applications Communications Control Applications High-Speed DSP Front-End Automotive Applications
