Overview
The AD9219ABCPZ-65, produced by Analog Devices Inc., is a quad, 10-bit analog-to-digital converter (ADC) designed for low cost, low power, small size, and ease of use. This ADC integrates four channels into a single package, making it ideal for applications where space is critical. It operates at conversion rates of up to 65 MSPS and is optimized for outstanding dynamic performance and low power consumption. The device is housed in a RoHS compliant, 48-lead Lead Frame Chip Scale Package (LFCSP) and is specified over the industrial temperature range of −40°C to +85°C.
