Overview
The AD9261BCPZRL7-10, manufactured by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) based on a continuous time sigma-delta (Σ-Δ) architecture. This ADC is designed to achieve a dynamic range of 87 dB over a 10 MHz input bandwidth, making it suitable for applications requiring high precision and wide bandwidth. The device features a resistive input impedance, which simplifies the requirements for the driver amplifier, and a 32× oversampled fifth-order continuous time loop filter that significantly attenuates out-of-band signals and aliases. This reduces the need for external filters at the input, enhancing the overall system simplicity and performance.
