The AD9258 is a dual, 14-bit, 125 MSPS analog-to-digital converter (ADC). The AD9258 is designed to support communications applications where high performance, combined with low cost, small size, and versatility, is desired.
The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth differential sample-and-hold analog input amplifiers that support a variety of user-selectable input ranges. An integrated voltage reference eases design consid-erations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.
