AD9281ARS

双通道8位分辨率的CMOS ADC Dual Channel 8-Bit Resolution CMOS ADC

Product Details

The AD9281 is a complete dual channel, 28 MSPS, 8-bit CMOS ADC. The AD9281 is optimized specifically for applications where close matching between two ADCs is required e.g., I/Q channels in communications applications. The 28 MHz sampling rate and wide input bandwidth will cover both narrow-band and spread-spectrum channels. The AD9281 integrates two 8-bit, 28 MSPS ADCs, two input buffer amplifiers, an internal voltage reference and multiplexed digital output buffers.
