AD774BBR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD774BBR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AD774BBR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。

PRODUCT DESCRIPTION

The AD674B and AD774B are complete 12-bit successive approximation analog-to-digital converters with three-state output buffer circuitry for direct interface to 8- and 16-bit microprocessor busses. A high-precision voltage reference and clock are included on chip, and the circuit requires only power supplies and control signals for operation. The AD674B and AD774B are pin-compatible with the industry standard AD574A, but offer faster conversion time and bus access speed than the AD574A and lower power consumption. The AD674B converts in 15 µs (maximum) and the AD774B converts in 8 µs (maximum).
