Overview
The AD9261BCPZ-10 is a high-performance, single 16-bit analog-to-digital converter (ADC) developed by Analog Devices Inc. This device is based on a continuous time (CT) sigma-delta (Σ-Δ) architecture, which enables it to achieve a dynamic range of 87 dBc over a 10 MHz input bandwidth. The AD9261 is designed to simplify the design process by integrating several key features, including a resistive input impedance, a 32× oversampled fifth-order continuous time loop filter, and on-chip decimation filters and sample rate converters. This makes it an ideal choice for applications requiring high accuracy and wide bandwidth.
