Product Details

The AD9262 is a dual, 16-bit analog-to-digital converter (ADC) based on a continuous time sigma-delta (Σ-Δ) architecture that achieves -87 dB of dynamic range over a 10 MHz input bandwidth.

The integrated features and characteristics unique to the continuous time Σ-Δ architecture significantly simplify its use and minimize the need for external components.

The AD9262 has a resistive input impedance that significantly relaxes the requirements of the driver amplifier. In addition, a 32× oversampled fifth-order continuous time loop filter significantly attenuates out of band signals and aliases, reducing the need for external filters at the input.

An external clock input or the integrated integer-N PLL provides the 640 MHz internal clock needed for the oversampled continuous time Σ-Δ modulator. On-chip decimation filters and sample rate converters reduce the modulator data rate from 640 MSPS to a user-defined output data rate between 30 MSPS to 160 MSPS, enabling a more efficient and direct interface.

The AD9262 incorporates an integrated dc correction and quadrature estimation block that corrects for gain and phase mismatch between the two channels. This functional block proves invaluable in complex signal processing applications such as direct conversion receivers.

The digital output data is presented in offset binary, Gray code, or twos complement format. A data clock output (DCO) is provided to ensure proper timing with the receiving logic. The AD9262 has the added feature of interleaving Channel A and Channel B data onto one 16-bit bus, simplifying on-board routing.

The ADC is available in three different bandwidth options of 2.5 MHz, 5 MHz, and 10 MHz, and operates on a 1.8 V analog supply and a 1.8 V to 3.3 V digital supply, consuming 600 mW. The AD9262 is available in a 64-lead LFCSP and is specified over the industrial temperature range (−40°C to +85°C).


  1. Continuous time Σ-Δ architecture efficiently achieves high dynamic range and wide bandwidth.
  2. Passive input structure reduces or eliminates the requirements for a driver amplifier.
  3. An oversampling ratio of 32× and high order loop filter provide excellent alias rejection reducing or eliminating the need for antialiasing filters.
  4. An integrated decimation filter, sample rate converter, PLL clock multiplier, and voltage reference provide ease of use.
  5. Integrated dc correction and quadrature error correction.
  6. Operates from a single 1.8 V analog power supply and 1.8 V to 3.3 V output supply.
