AD9649-80 14-bit, 20/40/65/80 MSPS, 1.8 V analog-to-digital converter
The AD9649 is a single-chip, single-channel, 14-bit, 20/40/65/80 MSPS analog-to-digital converter (ADC) that operates from a 1.8 V supply and has built-in high-performance sample-hold circuitry and an on-chip reference source.
It features a multi-stage differential pipeline architecture with built-in output error correction logic that provides 14-bit accuracy at 80 MSPS data rates and ensures code loss-free over the entire operating temperature range.
The ADC has a variety of built-in features that allow for optimal device flexibility and minimal system cost, such as programmable clock and data alignment, generation of programmable digital test codes, and more. Available digital test codes include built-in fixed and pseudo-random codes, as well as user-defined test codes entered via the Serial Port Interface (SPI).
A differential clock input with selectable 1, 2, or 4 frequency ratios is used to control all internal conversion cycles.
The digital output data format is offset binary, gray code, or binary complement. A data output clock (DCO) is used to ensure that the receive logic has the correct latching timing. Supports 1.8 V and 3.3 V CMOS levels.
The AD9649 is available in a 32-pin LFCSP package, is RoHS compliant, and is rated for an industrial temperature range of −40°C to +85°C.
