Overview
The AD9248BCPZRL-65, produced by Analog Devices Inc., is a high-performance, dual 14-bit analog-to-digital converter (ADC) designed for a wide range of applications. This ADC operates on a single 3 V supply (2.7 V to 3.6 V) and is available in a 64-lead LFCSP package. It features dual high-performance sample-and-hold amplifiers (SHAs) and an integrated voltage reference, making it suitable for various high-speed data acquisition tasks.
The AD9248 uses a multistage differential pipelined architecture with output error correction logic to ensure 14-bit accuracy and guarantee no missing codes over the full operating temperature range of -40°C to +85°C. This component is particularly useful in applications requiring high-speed, low-power, and high-precision data conversion.
