Overview
The AD9229BCPZ-50 is a quad, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed for low cost, low power consumption, and small size, making it ideal for applications where space and power efficiency are critical. The AD9229 operates at a conversion rate of up to 50 MSPS 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 is packaged in a Pb-free, 48-lead LFCSP package and is specified over the industrial temperature range of –40°C to +85°C.
