AD9648BCPZ-105

GENERAL DESCRIPTION

The AD9648 is a monolithic, dual-channel, 1.8 V supply, 14-bit, 105 MSPS/125 MSPS analog-to-digital converter (ADC). It features a high performance sample- and-hold circuit and on chip voltage reference.
The product uses multistage differential pipeline architecture with output error correction logic to provide 14-bit accuracy at 125 MSPS data rates and to guarantee no missing codes over the full operating temperature range.
