Overview
The AD9262BCPZ is a dual-channel, 16-bit analog-to-digital converter (ADC) developed by Analog Devices Inc. It is based on a continuous time sigma-delta (Σ-Δ) architecture, which achieves a dynamic range of -87 dB over a 10 MHz input bandwidth. This ADC is designed to simplify its use and minimize the need for external components, thanks to its integrated features such as a resistive input impedance, a 32× oversampled fifth-order continuous time loop filter, and integrated decimation filters and sample rate converters.
The AD9262BCPZ operates on a 1.8 V analog supply and a 1.8 V to 3.3 V digital supply, consuming 600 mW. It is available in a 64-lead LFCSP package and is specified over the industrial temperature range of -40°C to +85°C.
