AD9201 双通道、20 MHz、10位分辨率CMOS ADC

AD9201: 双通道、20 MHz、10位分辨率CMOS ADC

AD9201是一款完整的双通道、20 MSPS、10位CMOS ADC，专门针对要求两个ADC高度匹配的应用（例如通信应用中的I/Q通道）进行了优化。20 MHz采样速率和宽输入带宽可涵盖窄带与扩频两种通道。AD9201集成两个10位、20 MSPS ADC、两个输入缓冲放大器、一个内部基准电压源和多路复用数字输出缓冲。

The AD9201 is a complete dual channel, 20 MSPS, 10-bit CMOS ADC. The AD9201 is optimized specifically for applications where close matching between two ADCs is required (e.g., I/Q channels in communications applications). The 20 MHz sampling rate and wide input bandwidth will cover both narrow-band and spread-spectrum channels. The AD9201 integrates two 10-bit, 20 MSPS ADCs, two input buffer amplifiers, an internal voltage reference and multiplexed digital output buffers.
