LTC2259-16

16-Bit, 80Msps Ultralow

Power 1.8V ADC

FEATURES

DESCRIPTION

The LTC^®2259-16 is a sampling 16-bit A/D converter de-

signed for digitizing high frequency, wide dynamic range

signals. It is perfect for demanding communications ap-

plications with AC performance that includes 73.1dB SNR

and 88dB spurious free dynamic range (SFDR). Ultralow

73.1dB SNR

88dB SFDR

Low Power: 89mW

Single 1.8V Supply

with excellent noise performance.

800MHz Full-Power Bandwidth S/H

Optional Data Output Randomizer

Optional Clock Duty Cycle Stabilizer

Shutdown and Nap Modes

DC specs include 4LSB INL (typical) and 0.5LSB DNL

(typical).

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.

Serial SPI Port for Conﬁguration

40-Pin (6mm × 6mm) QFN Package

APPLICATIONS

–

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 allows high

performance at full speed for a wide range of clock duty

cycles.
