Overview
The AD9248BCPZ-65 is a high-performance, dual-channel, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to operate at sample rates of up to 65 million samples per second (MSPS) and is suitable for a wide range of applications requiring high-speed and high-accuracy data conversion.
Fabricated on an advanced CMOS process, the AD9248 features dual high-performance sample-and-hold amplifiers and an integrated voltage reference. It 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.
