AD9434-370EBZ
The AD9434 is a 12-bit single-chip sampled analog-to-digital converter (ADC) optimized for high performance, low power consumption, and ease of use. With slew rates of up to 500 MSPS, the device offers excellent dynamic performance for wideband carriers and wideband systems. All required functions are integrated on-chip, including a sample retainer and a voltage reference, to provide a complete signal conversion solution. The VREF pin can be used to monitor the internal reference or to provide an external reference (the external reference mode must be enabled via the SPI port).
The ADC requires a 1.8 V analog supply and a differential clock signal to maximize its performance. The digital outputs are LVDS (ANSI-644) compliant and support binary 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-pin LFCSP package with a temperature range of -40°C to +85°C industrial temperature range. 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 and 250 MHz input.
2. Low power consumption.
Power consumption is only 660 mW at 500 MSPS.
3. Easy to use.
LVDS output data and output clock signals allow interfacing with current FPGAs. The on-chip reference and sample-hold feature provide flexibility in system design, while a single 1.8 V supply simplifies system power design.
4. Serial port control
The standard serial port interface supports various product functions such as data formatting, power saving mode, gain adjustment, and generating output test codes.
5. The AD9434 is pin-compatible with the AD9230 and can replace existing ADCs in many applications with minimal design changes.
