3 Description
The ADC3544 device is a low-noise, ultra-low
power, 14-bit, 125-MSPS, high-speed analog-todigital
converter (ADC). Designed for low power
consumption, the device delivers a noise spectral
density of –153 dBFS/Hz, combined with a good
linearity and dynamic range. The ADC3544 offers
IF sampling support, which make these devices an
excellent choice for a wide range of applications.
High-speed control loops benefit from the short
latency of only one clock cycle. The ADC consumes
only 97 mW/ch at 125 MSPS, and the power
consumption scales well with lower sampling rates.
The ADC3544 uses an SDR or DDR interface to
output the data offering the lowest power digital
interface, together with the flexibility to minimize the
number of digital interconnects. These devices are
a pin-to-pin compatible family with different speed
grades. These devices support the extended industrial
temperature range of –40°C to 105⁰C.
