Overview
The AD9233BCPZ-125 is a high-performance, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic device operates from a single 1.8 V power supply and features a separate digital output driver supply that can accommodate 1.8 V to 3.3 V logic families. It is designed with a multistage differential pipeline architecture and includes an on-chip voltage reference and sample-and-hold amplifier, ensuring 12-bit accuracy at sample rates up to 125 MSPS. The AD9233BCPZ-125 is packaged in a 48-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C.
