AD7880: CMOS、+5 V单电源、低功耗、12位采样ADC
AD7880是一款高速、低功耗、12位模数转换器（ADC），采用+5 V单电源供电。它内置一个3 微秒（µs）采样保持放大器、一个12 微秒（µs）逐次逼近型ADC、多功能接口逻辑和一个多重输入范围电路，还具有省电特性。采用+5 V单电源供电时，利用内部电阻网络，该器件可输入单极性和双极性两种信号。通过快速总线可访问现代微处理器和数字信号处理器。AD7880的总吞吐时间为15 µs，在采样频率为66 kHz时，可以转换最高33 kHz的全功率信号。除线性度、满量程和失调误差等传统直流精度规格外，AD7880的动态性能参数也做了全面详细规定，包括谐波失真和信噪比。AD7880采用ADI公司的线性兼容CMOS （LC2MOS）工艺制造，这是一种将精密的双极性电路与低功耗CMOS逻辑结合在一起的混合工艺技术。该器件提供两种封装：24引脚、0.3英寸宽、塑料或密封双列直插式封装（DIP）和24引脚小型SOIC封装
The AD7880 is a high speed, low power, 12-bit A/D converter which operates from a single +5 V supply. It consists of a 3 µs track/hold amplifier, a 12 µs successive-approximation ADC, versatile interface logic and a multiple-input range circuit. The part also includes a power save feature.An internal resistor network allows the part to accept both unipolar and bipolar input signals while operating from a single +5 V supply. Fast bus access to modern microprocessors and digital signal processors.The AD7880 features a total throughput time of 15 µs and can convert full power signals up to 33 kHz with a sampling frequency of 66 kHz.In addition to the traditional dc accuracy specifications such as linearity, full scale and offset errors, the AD7880 is also fully specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio.The AD7880 is fabricated in Analog Devices' Linear Compatible CMOS (LC2MOS) process, a mixed technology process that combines precision bipolar circuits with low power CMOS logic. The part is available in a 24-pin, 0.3 inch wide, plastic or hermetic dual-in-line package (DIP) as well as a small 24-lead SOIC package.
