12位1.8V的模拟到数字转换器AD9233数据表

　　The AD9233 is a monolithic， single 1.8 V supply， 12-bit， 80 MSPS/ 105 MSPS/125 MSPS analog-to-digital converter （ADC）， featuring a high performance sample-and-hold amplifier （SHA） and onchip voltage reference. The product uses a multistage differential pipeline architecture with output error correction logic to provide 12-bit accuracy at 125 MSPS data rates and guarantees no missing codes over the full operating temperature range. The wide bandwidth， truly differential SHA allows a variety of user-selectable input ranges and offsets， including single-ended applications. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist rate. Combined with power and cost savings over previously available ADCs， the AD9233 is suitable for applications in communications， imaging， and medical ultrasound. A differential clock input controls all internal conversion cycles. A duty cycle stabilizer （DCS） compensates for wide variations in the clock duty cycle while maintaining excellent overall ADC performance.
