FEATURES

DESCRIPTION

The LTC^®2152-12/LTC2151-12/LTC2150-12 are a family

of 250Msps/210Msps/170Msps 12-bit A/D converters

designedfordigitizinghighfrequency,widedynamicrange

signals. They are perfect for demanding communications

applications with AC performance that includes 68.5dB

SNR and 90dB spurious free dynamic range (SFDR). The

1.25GHz input bandwidth allows the ADC to undersample

highinputfrequencieswithgoodperformance.Thelatency

is only six clock cycles.

68.5dB SNR

90dB SFDR

Low Power: 347mW/333mW/306mW Total

Single 1.8V Supply

DDR LVDS Outputs

Easy-to-Drive 1.5V Input Range

P-P

1.25GHz Full Power Bandwidth S/H

Optional Clock Duty Cycle Stabilizer

Low Power Sleep and Nap Modes

Serial SPI Port for Conﬁguration

Pin-Compatible 14-Bit Versions

40-Lead (6mm × 6mm) QFN Package

DCspecsinclude 0.26LSBINL(typ), 0.16LSBDNL(typ)

and no missing codes over temperature. The transition

noise is 0.54LSB

RMS

The digital outputs are double-data rate (DDR) LVDS.

APPLICATIONS

–

The ENC and ENC inputs can be driven differentially with

asinewave,PECL,LVDS,TTL,orCMOSinputs.Anoptional

clock duty cycle stabilizer allows high performance at full

speed for a wide range of clock duty cycles.
