Low Power Dual ADCs  
FEATURES  
DESCRIPTION  
The LTC®2195/LTC2194/LTC2193 are 2-channel, simul-  
taneous sampling 16-bit A/D converters designed for  
digitizing high frequency, wide dynamic range signals.  
They are perfect for demanding communications applica-  
tions with AC performance that includes 76.8dB SNR and  
90dB spurious free dynamic range (SFDR). Ultralow jitter

To minimize the number of data lines the digital outputs  
are serial LVDS. Each channel outputs two bits or four bits  
at a time. At lower sampling rates there is a one bit per  
channel option. The LVDS drivers have optional internal  
termination and adjustable output levels to ensure clean  
signal integrity.

The ENC and ENC inputs may be driven differentially or  
single ended with a sine wave, PECL, LVDS, TTL or CMOS  
inputs. An internal clock duty cycle stabilizer allows high  
performance at full speed for a wide range of clock duty  
cycles.
