AD9268

16-Bit, 80 MSPS/105 MSPS/125 MSPS, 1.8 V Dual Analog-to-Digital Converter (ADC)

Analog Devices 

GENERAL DESCRIPTION

The AD9268 is a dual, 16-bit, 80 MSPS/105 MSPS/125 MSPS

analog-to-digital converter (ADC). The AD9268 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

16-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 AD9268 is available in a 64-lead LFCSP and is specified over

the industrial temperature range of −40°C to +85°C.
