ADI AD9640ABCPZRL7-80

The AD9640 is a dual 14-bit, 80/105/125/150 MSPS analog-to-digital converter (ADC). The AD9640 is designed to support communications applications where low cost, small size, and versatility are desired. The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth.
