Overview
The AD9262BCPZ-10 is a high-performance, dual 16-bit analog-to-digital converter (ADC) from Analog Devices Inc., 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 a variety of high-precision applications. The device simplifies system design by minimizing the need for external components, thanks to its integrated features such as a resistive input impedance and a 32× oversampled fifth-order continuous time loop filter. The AD9262BCPZ-10 operates with an external clock input or an integrated integer-N PLL to generate the necessary internal clock frequency.
