AD9434-370EBZ
The AD9434 is a 12-bit monolithic sampling analogconverter(ADC), optimized for high performance, low power, and ease of use. With slew rates up to 500 MSPS, the device has excellent dynamic performance for wideband carriers and wideband systems. All necessary functions, including a sample-and-hold and voltage reference, are integrated on-chip to provide a complete signal conversion solution. The VREF pin can be used to monitor the internal reference voltage or to provide an external reference voltage (external reference mode must be enabled through the SPI port).
The ADC requires a 1.8 V analog supply and differential clock signals to fully operate in order to operate at full performance. The digital outputs are LVDS (ANSI-644) compatible and support twos complement, offset binary, or gray code formats. The ADC also provides a data clock output for proper timing of output data.
The AD9434 is manufactured using an advanced BiCMOS process and is available in a 56-lead LFCSP package and is specified over the industrial temperature range of -40°C to +85°C. The device is protected by U.S. and international patents.

Product Focus
1. High performance.
The signal-to-noise ratio is maintained at 65 dBFS at 500 MSPS at 250 MHz input.
2. Low power consumption.
Power consumption at 500 MSPS is only 660 mW.
3. Easy to use.
LVDS output data and output clock signals allow interfacing with existing FPGAs. The on-chip reference and sample-and-hold function provide system design flexibility, while a single 1.8 V supply simplifies system power supply design.
4. Serial port control
The standard serial port interface supports various product functions such as data formatting, power-down mode, gain adjustment, and output test code generation.
5. The AD9434 is pin-compatible with the AD9230 and can replace existing ADCs in many applications with minimal design changes.
