AD9684BBPZRL7-500

ADC Dual Pipelined 500MSPS 14Bit Serial 196Pin BGA T/R

Product Details

The AD9684 is a dual, 14-bit, 500 MSPS ADC. The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed for sampling wide bandwidth analog signals. The AD9684 is optimized for wide input bandwidth, a high sampling rate, excellent linearity, and low power in a small package.

The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth buffered inputs, supporting a variety of user selectable input ranges. An integrated voltage reference eases design considerations. Each ADC data output is internally connected to an optional decimate by 2 block.

The analog input and clock signals are differential inputs. Each ADC data output is internally connected to two digital downconverters DDCs. Each DDC consists of four cascaded signal processing stages: a 12-bit frequency translator NCO, and three half-band decimation filters supporting a divide by factor of two, four, and eight.
