The LTC®2262-12 is a sampling 12-bit A/D converter

designedfordigitizinghighfrequency,widedynamicrange

signals.TheLTC2262-12isperfectfordemandingcommu-

nications applications with AC performance that includes

frequencies with excellent noise performance.

DC specs include ±0.3LSB INL (typical), ±0.1LSB DNL

(typical) and no missing codes over temperature. The

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.

or single-ended with a sine wave, PECL, LVDS, TTL or

CMOS inputs. An optional clock duty cycle stabilizer al-

lows high performance at full speed for a wide range of

clock duty cycles.
