The LTC

®2142-12/LTC2141-12/LTC2140-12 are 2-channel

simultaneous sampling 12-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 70.8dB SNR and

89dB spurious free dynamic range (SFDR). Ultralow jitter

of 0.08psRMS allows undersampling of IF frequencies with

excellent noise performance.

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

and no missing codes over temperature. The transition

noise is 0.3LSBRMS.

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.
