The AD9641 is a 14-bit, 80 MSPS/155 MSPS analog-to-digital converter (ADC) with a high speed serial output interface. The AD9641 is designed to support communications applications where high performance, combined with low cost, small size, and versatility, is desired. The JESD204A high speed serial interface reduces board routing requirements and lowers pin count requirements for the receiving device.The ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. The ADC features wide bandwidth, differential sample-and-hold, analog input amplifiers that support a variety of user-selectable input ranges. An integrated voltage reference eases the design considerations. A duty cycle stabilizer (DCS) is provided to compensate for variations in the ADC clock duty cycle, allowing the converter to maintain excellent performance.Flexible power-down options allow significant power savings, when desired. Programming for setup and control is accomplished using a 3-wire SPI-compatible serial interface. The AD9641 is available in a 32-lead LFCSP and is specified over the industrial temperature range of -40°C to +85°C.
