Product Summary

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.

Parametrics

Product Highlights

  1. On-chip dither option for improved SFDR performance with low power analog input.
  2. Proprietary differential input that maintains excellent SNR performance for input frequencies up to 300 MHz.
  3. Operation from a single 1.8 V supply and a separate digital output driver supply accommodating 1.8 V CMOS or LVDS outputs.
  4. Standard serial port interface (SPI) that supports various product features and functions, such as data formatting (offset binary, twos complement, or gray coding), enabling the clock DCS, power-down, test modes, and voltage reference mode.
  5. Pin compatibility with the AD9258, allowing a simple migration from 16 bits to 14 bits. The AD9268 is also pin compatible with the AD9251, AD9231, and AD9204 family of products for lower sample rate, low power applications.
