Analog Devices AD9144, AD9625 and AD9680 converters

Analog Devices has released a digital-to-analog converter, an analog-to-digital converter and a dual analog-to-digital converter. The devices are suitable for a range of applications, including 3G/4G cellular infrastructure, aerospace and defence, and instrumentation.

The AD9144 is a quad, 16-bit, high-dynamic-range DAC with a maximum sample rate of 2.8 GS/s that permits a multicarrier generation up to the Nyquist frequency. An optional serial port interface provides for programming or read-back of many internal parameters. Full-scale output current can be programmed over a typical range of 13.9 to 27 mA.

The AD9625 is a 12-bit monolithic sampling ADC that operates at conversion rates of up to 2.5 GS/s and is designed for sampling wide bandwidth analog signals up to the second Nyquist zone. The combination of wide input bandwidth, high sampling rate and good linearity makes the product suitable for spectrum analysers, data acquisition systems and a range of military electronics applications, such as radar and electronic countermeasures.

The AD9680 is a dual, 14-bit, 1 GSPS ADC with an on-chip buffer and sample-and-hold circuit designed for low power, small size and ease of use. It is designed for sampling wide bandwidth analog signals of up to 2 GHz. The product includes buffered inputs with programmable input termination for easier filter design and implementation, and a flexible SPI controls various product features to meet system requirements.
