Product Details

The AD9613 is a dual 12-bit, analog-to-digital converter (ADC) with sampling speeds up to 250 MSPS. The AD9613 is designed to support communications applications where low cost, small size, wide bandwidth and versatility are desired.

The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference 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.

The ADC output data are routed directly to the two external 12- bit LVDS output ports and formatted either as interleaved or channel multiplexed.

Flexible power-down options allow significant power savings, when desired.

Programming for setup and control are accomplished using a 3- wire SPI-compatible serial interface.

The AD9613 is available in a 64-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C.


  1. Integrated dual, 12-bit, 170 MSPS/210 MSPS/250 MSPS ADCs.
  2. Fast overrange and threshold detect.
  3. Proprietary differential input maintains excellent SNR performance for input frequencies up to 400 MHz.
  4. SYNC input allows synchronization of multiple devices.
  5. 3-pin, 1.8V SPI port for register programming and register readback.
  6. Pin compatibility with the AD9643, allowing a simple migration up to 14 bits, and with the AD6649 and the AD6643.

Virtual Eval - BETA

Virtual Eval is a web application to assist designers in product evaluation of ADCs, DACs, and other ADI products. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, response plots, and more.
