PRODUCT HIGHLIGHTS
1. The AD9266 operates from a single 1.8 V analog power
supply and features a separate digital output driver supply
to accommodate 1.8 V to 3.3 V logic families.
2. The patented sample-and-hold circuit maintains excellent
performance for input frequencies up to 200 MHz and is
designed for low cost, low power, and ease of use.
3. A standard serial port interface supports various product
features and functions, such as data output formatting,
internal clock divider, power-down, DCO and data output
(D15_D14 to D1_D0) timing and offset adjustments, and
voltage reference modes.
4. The AD9266 is packaged in a 32-lead RoHS-compliant
LFCSP that is pin compatible with the AD9609 10-bit
ADC, the AD9629 12-bit ADC, and the AD9649 14-bit
ADC, enabling a simple migration path between 10-bit and
16-bit converters sampling from 20 MSPS to 80 MSPS.
