AD9649BCPZ-20

GENERAL DESCRIPTION

The AD9649 is a monolithic, single channel 1.8 V supply, 14-bit, 20/40/65/80 MSPS analog-to-digital converter (ADC). It features a high performance sample- and-hold circuit and an on-chip voltage reference.
The product uses multistage differential pipeline architecture with output error correction logic to provide 14-bit accuracy at 80 MSPS data rates and to guarantee no missing codes over the full operating temperature range.
