The LTC

®2270 is a two-channel simultaneous sampling

16-bit A/D converter designed for digitizing high frequency,

wide dynamic range signals. It is perfect for demanding

applications with AC performance that includes 84.1dB

SNR and 99dB spurious free dynamic range (SFDR).

DC specs include ±1LSB INL (typ), ±0.2LSB DNL (typ)

and no missing codes over temperature. The transition

noise is 1.44LSBRMS.

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-

lows high performance at full speed for a wide range of

clock duty cycles.
