产品信息

描述The THS1206 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 THS1206 consists of four analog inputs, which are sampled simultaneously. These inputs can be selected individually and configured to single-ended or differential inputs. An integrated 16 word deep FIFO allows the storage of data in order to take the load off of the processor connected to the ADC. 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. Two different conversion modes can be selected. In single conversion mode, a single and simultaneous conversion of up to four inputs can be initiated by using the single conversion start signal (CONVST)\. The conversion clock in single conversion mode is generated internally using a clock oscillator circuit. In continuous conversion mode, an external clock signal is applied to the CONV_CLK input of the THS1206. The internal clock oscillator is switched off in continuous conversion mode. The THS1206C is characterized for operation from 0°C to 70°C, the THS1206I is characterized for operation from –40°C to 85°C, the THS1206Q is characterized to meet the rigorous requirements of the automotive environment from –40°C to 125°C, and the THS1206M is characterized for operation over the full military temperature range of –55°C to 125°C.特性High-Speed 6 MSPS ADC 4 Analog Inputs Simultaneous Sampling of 4 Single-Ended Signals or 2 Differential Signals or Combination of Both Differential Nonlinearity Error: ±1 LSB Integral Nonlinearity Error: ±1.5 LSB Signal-to-Noise and Distortion Ratio: 68 dB at fI = 2 MHz Auto-Scan Mode for 2, 3, or 4 Inputs 3-V or 5-V Digital Interface Compatible Low Power: 216 mW Max 5-V Analog Single Supply Operation Internal Voltage References ...50 PPM/°C and ±5% Accuracy Glueless DSP Interface Parallel µC/DSP Interface Integrated FIFO Available in TSSOP Package Pin Compatible Upgrade to THS10064 APPLICATIONS Radar Applications Communications Control Applications High-Speed DSP Front-End Automotive Applications
