Overview
The AD9235BCPZRL7-40 is a 12-bit, high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates on a single 3 V power supply and is available in a 32-lead Lead Frame Chip Scale Package (LFCSP). It features a multistage differential pipelined architecture with output error correction logic, ensuring 12-bit accuracy at data rates of 20, 40, and 65 MSPS. The AD9235 is designed for applications requiring high speed, low power consumption, and excellent signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR).
