ADC102S021 - 双通道、50 ksps 至 200 ksps、10 位 A/D 转换器 - 精密ADC(<=10MSPS) - 模数转换器 - TI公司（Texas Instruments，德州仪器）
The ADC102S021 is a low-power, two-channel CMOS 10-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC102S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input signals at inputs IN1 and IN2.
The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many common DSP serial interfaces.
The ADC102S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 1.94 mW and 6.9 mW, respectively. The power-down feature reduces the power consumption to just 0.12 µW using a +3V supply, or 0.47 µW using a +5V supply.
The ADC102S021 is packaged in an 8-lead VSSOP package. Operation is specified over the industrial temperature range of −40°C to +85°C.
