AD7827: 3 V/5 V、1 MSPS、8位、串行接口采样ADC
AD7827是一款高速、单通道、低功耗模数转换器(ADC),最大吞吐量为1 MSPS,采用3 V或5 V单电源供电。该器件内置一个采样保持放大器、一个2.5 V(2%容差)片内基准电压源、一个420 ns 的8位半快速型(half-flash)ADC和一个串行接口,该串行接口与大多数数字信号处理器(DSP)的串行接口兼容。AD7827的吞吐量取决于DSP串行接口的时钟速度。
The AD7827 is a high speed, single channel, low power, analog-to- digital converter with a maximum throughput of 1 MSPS that operates from a single 3 V or 5 V supply. The AD7827 contains a track/hold amplifier, an on-chip 2.5 V reference (2% tolerance), a 420 ns 8-bit half-flash ADC and a serial interface. The serial interface is compatible with the serial interfaces of most DSPs (Digital Signal Processors). The throughput rate of the AD7827 is dependent on the clock speed of the DSP serial interface.
