DescripTion

The LTC^®2261-14/LTC2260-14/LTC2259-14 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

Pin Compatible 14-Bit and 12-Bit Versions

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.

Communications

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 allows high

performance at full speed for a wide range of clock duty

cycles.
