GENERAL DESCRIPTION
The AD9258 is a dual, 14-bit, 80 MSPS/105 MSPS/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.

The ADC output data can be routed directly to the two external
14-bit output ports. These outputs can be set to either 1.8 V CMOS
or LVDS.
Flexible power-down options allow significant power savings,
when desired.
Programming for setup and control is accomplished using a 3-wire
SPI-compatible serial interface.
The AD9258 is available in a 64-lead LFCSP and is specified over
the industrial temperature range of −40°C to +85°C.
