FeaTures

DescripTion

The LTM^®9011-14/LTM9010-14/LTM9009-14 are 8-channel,

simultaneous sampling 14-bit A/D converters designed

for digitizing high frequency, wide dynamic range signals.

AC performance includes 73.1dB SNR and 88dB spurious

free dynamic range (SFDR). Low power consumption per

channel reduces heat in high channel count applications.

Integrated bypass capacitance and flow-through pinout

reduces overall board space requirements.

8-Channel Simultaneous Sampling ADC

73.1dB SNR

88dB SFDR

Low Power: 140mW/113mW/94mW per Channel

Single 1.8V Supply

Serial LVDS Outputs: 1 or 2 Bits per Channel

Selectable Input Ranges: 1V to 2V

P-P

800MHz Full Power Bandwidth S/H

Shutdown and Nap Modes

DC specs include 1LSB INL (typ), 0.3LSB DNL (typ) and

no missing codes over temperature. The transition noise

Components

is a low 1.2LSB

RMS

The digital outputs are serial LVDS to minimize the num-

ber of data lines. Each channel outputs two bits at a time

(2-lane mode). At lower sampling rates there is a one bit

per channel option (1-lane mode).

applicaTions

Communications

–

The ENC and ENC inputs may be driven differentially

or single-ended with a sine wave, PECL, LVDS, TTL, or

CMOS inputs. An internal clock duty cycle stabilizer al-

lows high performance at full speed for a wide range of

clock duty cycles.
