The AD9261 is a 16-bit analog-to-digital converter (ADC) based on a continuous time sigma-delta (Σ-Δ) architecture that achieves 86 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 AD9261 has a resistive input impedance that significantly relaxes the requirements of the driver amplifier. In addition, a 32× oversampled 5th-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 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 AD9261 operates on a 1.8 V analog supply and a 1.8 V to 3.3 V digital supply, consuming 375 mW. The AD9261 is available in a 48-lead LFCSP and is specified over the industrial temperature range (−40°C to +85°C).
Product Highlights
