AD7819YR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD7819YR属于集成电路（IC）的模数转换器（ADC）。由亚德诺半导体技术有限公司制造生产的AD7819YR模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

GENERAL DESCRIPTION

The AD7819 is a high speed, microprocessor-compatible, 8-bit analog-to-digital converter with a maximum throughput of 200 kSPS. The converter operates off a single 2.7 V to 5.5 V supply and contains a 4.5 µs successive approximation A/D converter, track/hold circuitry, on-chip clock oscillator and 8-bit wide parallel interface. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. Using only address decoding logic the AD7819 is easily mapped into the microprocessor address space.
