ADI推出16位,25 MSPS/65 MSPS/80 MSPS/105 MSPS的模擬到數(shù)字轉(zhuǎn)換器

The AD9650 is a dual, 16-bit, 25 MSPS/65 MSPS/80 MSPS/ 105 MSPS analog-to-digital converter (ADC) designed for digitizing high frequency, wide dynamic range signals with input frequencies of up to 300 MHz.

The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth, differential sample-and-hold analog input amplifiers, and shared integrated voltage reference, which eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance.

The ADC output data can be routed directly to the two external 16-bit output ports or multiplexed on a single 16-bit bus. These outputs can be set to either 1.8 V CMOS or LVDS.

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 AD9650 is available in a 64-lead LFCSP and is specified over the industrial temperature range of −40°C to +85°C.
