Analog Devices AD9249 analog-to-digital converter

Analog Devices has released the analog-to-digital converter AD9249, a 16-channel, 14-bit ADC with an on-chip sample-and-hold circuit designed for low cost, low power, small size and ease of use.

The device operates at a conversion rate of up to 65 MSPS and is optimised for high dynamic performance and low power in applications where a small package size is critical. The product requires a single 1.8 V power supply and an LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.

The device automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. Data clock outputs for capturing data on the output and frame clock outputs for signalling a new output byte are provided. Individual channel power-down is supported and the device typically consumes less than 2 mW when all channels are disabled.

The ADC contains a programmable clock, data alignment and digital test pattern generation. It is suitable for medical imaging, communications receivers and multichannel data acquisition applications.
