GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9650 is a dual, 16-bit, 25 MSPS/65 MSPS/80 MSPS/

105 MSPS analog-to-digital converter (ADC) designed for

digitizing high frequency, wide dynamic range signals with

input frequencies of up to 300 MHz.

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, and test modes.

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, and shared integrated voltage reference,

which eases design considerations. A duty cycle stabilizer is

provided to compensate for variations in the ADC clock duty

cycle, allowing the converters to maintain excellent performance.

5. Pin compatible with the AD9268 and other dual families,

AD9269, AD9251, AD9231, and AD9204. This allows a

simple migration across resolutions and bandwidth.

The ADC output data can be routed directly to the two external

16-bit output ports or multiplexed on a single 16-bit bus. These

outputs can be set to either 1.8 V CMOS or LVDS.
