LTC2194/LTC2193

16-Bit, 125/105/80Msps

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

RMS

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.

APPLICATIONS

Communications

Cellular Base Stations

Software-Deﬁned Radios

Portable Medical Imaging

Multi-Channel Data Acquisition

–

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.
