LTC2270

16-Bit, 20Msps

Low Noise Dual ADC

FEATURES

DESCRIPTION

Two-Channel Simultaneously Sampling ADC

The LTC^®2270 is a two-channel simultaneous sampling

16-bitA/Dconverterdesignedfordigitizinghighfrequency,

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).

84.1dB SNR (46μV

99dB SFDR

2.ꢀLSB INL(Max)

RMS

Low Power: 160mW Total, 80mW per Channel

Single 1.8V Supply

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

and no missing codes over temperature. The transition

RMS

200MHz Full Power Bandwidth S/H

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.

Pin Compatible with

LTC2180: 16-Bit, 25Msps, 78mW

–

LTC2140-14: 14-Bit, 25Msps, 50mW

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.
