Product Details

The AD9655 is a dual, 16-bit, 125 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

The ADC requires a single 1.8 V power supply and an LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. External reference or driver components are not required for many applications.

The ADC automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. A data clock output (DCO) for capturing data on the output and a frame clock output (FCO) for signaling a new output byte are provided. Individual channel power-down is supported.

The AD9655 typically consumes less than 2 mW in SPI powerdown mode. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).

The AD9655 is available in a RoHS-compliant, 32-lead LFCSP. It is specified over the industrial temperature range of −40°C to +85°C. This device is protected by a U.S. patent.

Product Highlights

  1. Small Footprint. Two ADCs are contained in a small, spacesaving package.
  2. Pin compatible to the AD9645 14-bit and AD9635 12-bit dual ADCs.
  3. Ease of use. A DCO operates at frequencies of up to 500 MHz and supports double data rate (DDR) operation.
  4. User Flexibility. The SPI control offers a wide range of flexible features to meet specific system requirements.

Product Details

The AD9655-125EBZ is an evaluation board for the AD9655, dual 16-bit ADC. This reference design provides the support circuitry to operate the device in its various modes and configurations. It is designed to interface directly with the HSC-ADC-EVALC data capture card, allowing users to download captured data for analysis. The VisualAnalog software package, which is used to interface with the device's hardware, allows users to download captured data for analysis with a user-friendly graphical interface. The SPIController software package is also compatible with this hardware, and allows the user to access the SPI programmable features of the AD9655. 


The AD9655 data sheet provides additional information related to device configuration and performance, and should be consulted when using these tools. All documents and VisualAnalog and SPIController are available at the High Speed ADC Evaluation Boards page. For additional information or questions, please email highspeed.converters@analog.com.
