Texas Instruments’ ADC344x family of analog-to-digital converters are high-linearity, ultra-low power, quad-channel, 14-bit resolution, 25-MSPS to 125-MSPS devices with the ability to support demanding, high input frequency signals with large dynamic range requirements make them ideal for use in high-speed data acquisition and generation as well as MRI, magnetic resonance imaging.

The ADC344x line feature a serial two-wire low-voltage differential signaling (LVDS) to reduce the number of interface lines and permit high system integration density, which, when combined with the serial LVDS’ two-wire interface, results in serialized data outputted over two LVDS pairs.

If system clock architecture is a concerning aspect of your design, the ADC344x family feature an input clock divider that provides flexibility for selecting the appropriate architecture while the SYSREF input enables entire system synchronization.

Another noteworthy aspect of the device is the internal phase-locked loop (PLL) which multiples the incoming ADC sampling clock to derive the bit clock that is used to serialize the 14-bit output data from each channel.

 Of course, what ties the package together is an ultra-low power consumption of 98 mW/Ch at 125 MSPS.
