FeaTures  
DescripTion  
The LTC®2258-14/LTC2257-14/LTC2256-14 are sam-  
pling 14-bit A/D converters designed for digitizing high  
frequency, wide dynamic range signals. They are perfect  
for demanding communications applications with AC  
performance that includes 74dB SNR and 88dB spurious

The digital outputs can be either full rate CMOS, double  
data rate CMOS, or double data rate LVDS. A separate  
output power supply allows the CMOS output swing to  
range from 1.2V to 1.8V.

The ENC and ENC inputs may be driven differentially  
or single ended with a sine wave, PECL, LVDS, TTL or  
CMOS inputs. An optional clock duty cycle stabilizer al-
