256-Channel Low Noise Current-to-Digital Converter

AS5911是一款超低噪声、256通道低功耗电容数字转换器，能够以最高灵敏度读取CT检测器的光电二极管。256个光电二极管的输出电流同时转换为数字信号，无死区时间，因此输入端没有电荷损失。AS5911将256通道的电流-电压积分和A/D转换功能结合在一个器件中。ADC结构采用低噪声积分器、粗量化器、采样保持器和精细量化器，可确保在0.5 μA输入电流范围内，输入相关噪声最低，最大为0.29 fC（低噪声模式）。ADC的输入电流范围可在0.5μA和1μA之间选择。 • 256-channel in 14 x 14 mm² FBGA package\n• Ultra-low noise of 0.29 fC at 0.5 μA input current in low noise mode\n• Lowest power dissipation of 1.25 mW per channel in low power mode\n• Adjustable integration time down to 51 μs (20 kSPS) at 20-bit resolution. Up to 26-bit at integration times of 1 m;
