Overview
The AD9229ABCPZ-50 is a quad, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed for low cost, low power, small size, and ease of use, making it ideal for applications where dynamic performance and compact design are critical. The AD9229 operates at up to a 50 MSPS conversion rate and features an on-chip sample-and-hold circuit. It requires a single 3 V power supply and supports TTL-/CMOS-compatible sample rate clocks. The ADC also includes features such as automatic multiplication of the sample rate clock for the appropriate LVDS serial data rate, a data clock (DCO) for capturing data, and a frame clock (FCO) trigger for signaling new output bytes. The device is available in a Pb-free, 48-lead LFCSP package and is specified over the industrial temperature range of –40°C to +85°C.
