AD9649-40 14-bit, 20/40/65/80 MSPS, 1.8 V analog-to-digital converter
The AD9649 is a monolithic, single, 14-bit, 20/40/65/80 MSPS analog-to-digital converter (ADC) that operates from a 1.8 V supply and contains high performance track-and-hold circuitry and an on-chip reference.
The multistage differential pipeline architecture with built-in output error correction logic provides 14-bit accuracy at 80 MSPS data rates and guarantees no missing codes over the entire operating temperature range.
The ADC includes features that provide optimal flexibility and minimal system cost, such as programmable clock and data alignment, and generation of programmable digital test patterns. Available digital test codes include built-in fixed and pseudo-random codes, as well as user-defined test codes input via the serial port interface (SPI).
A differential clock input with selectable divide-by-1, 2, or 4 divide-by-1 ratios controls all internal conversion cycles.
The digital output data is formatted as offset binary, gray code, or twos complement. A data output clock (DCO) is used to ensure that the receive logic has the correct latch timing. 1.8 V and 3.3 V CMOS levels are supported.
The AD9649 is available in a 32-lead LFCSP package, RoHS compliant, and is specified over the industrial temperature range of −40°C to +85°C.
