Overview
The AD9246BCPZ-105 is a high-performance, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. It operates from a single 1.8 V power supply and features a separate digital output driver supply to accommodate 1.8 V to 3.3 V logic families. This monolithic ADC uses a multistage differential pipeline architecture with output error correction logic, ensuring 14-bit accuracy at sampling rates of up to 105 MSPS. The device includes a high-performance sample-and-hold amplifier (SHA) and an on-chip voltage reference, making it suitable for various applications requiring high-speed and high-precision data conversion.
