Industry Leading SFDR from DC to 1GHz
The LTC®2000 is a family of 16-/14-/11-bit 2.5Gsps current steering DACs with exceptional spectral purity from
DC to 1GHz. These DACs feature wide output bandwidth and adjustable output current up to 60mA, making them ideal
for generating high frequency or broadband signals. The double data rate (DDR) LVDS interface requires 16 lanes
for up to 1.25Gsps data rate or 32 lanes for operation up to 2.5Gsps.
