AD7623:16位、1.33 MSPS PulSAR(R) ADC

AD7623是一款16位、1.33 MSPS、电荷再分配SAR型、全差分模数转换器(ADC),采用2.5 V单电源供电。它内置一个16位高速采样ADC、一个内部转换时钟、一个内部基准电压源(和缓冲)、纠错电路,以及串行和并行系统接口端口。功耗随吞吐量按比例自动变化,因此该器件非常适合电池供电应用。它提供48引脚薄型四方扁平封装(LQFP)和引脚架构芯片级封装(LFCSP_VQ)两种形式,工作温度范围为-40°C至+85°C。

The AD7623 is a 16-bit, 1.33 MSPS, charge redistribution SAR, fully differential analog-to-digital converter (ADC) that operates from a single 2.5 V power supply. It contains a high speed 16-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and both serial and parallel system interface ports. Power consumption is automatically scaled with throughput, making it ideal for battery-powered applications. It is available in 48-lead, low profile quad flat package (LQFP) and a lead frame chip-scale (LFCSP_VQ) package. Operation is specified from -40°C to +85°C.

AD7623 亮点
  1. 高吞吐量:AD7623是一款1.33 MSPS、电荷再分配、16位SAR ADC。
  2. 出色的线性度:AD7623 16位无失码。
  3. 内部基准电压:AD7623具有一个2.048 V内部基准电压,典型漂移量为±7 ppm/°C。
  4. 单电源供电:AD7623采用2.5 V单电源供电,功耗典型值为45 mW,其功耗会随吞吐量降低而减少。
  5. 串行或并行接口:多功能并行(16位或8位总线)或双线串行接口配置,2.5 V、3.3 V或5 V逻辑兼容。
  1. Fast Throughput: The AD7623 is a 1.33 MSPS, charge redistribution, 16-bit SAR ADC.
  2. Superior Linearity: The AD7623 has no missing 16-bit code.
  3. Internal Reference: The AD7623 has a 2.048 V internal reference with a typical drift of ±7 ppm/°C.
  4. Single-Supply Operation: The AD7623 operates from a 2.5 V single supply and typically dissipates 45 mW. Its power dissipation decreases with the throughput.
  5. Serial or Parallel Interface: Versatile parallel (16- or 8-bit bus) or 2-wire serial interface arrangement compatible with 2.5 V, 3.3 V, or 5 V logic.
