LTM2173-14

14-Bit, 80Msps Low

Power Quad ADC

FEATURES

DESCRIPTION

The LTM^®2173-14 is a 4-channel, simultaneous sam-

pling 14-bit A/D converter designed for digitizing high

frequency, wide dynamic range signals. AC performance

includes 73dB 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.

4-Channel Simultaneous Sampling ADC

73dB SNR

88dB SFDR

Low Power: 96mW 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

Serial SPI Port for Configuration

Internal Bypass Capacitance, No External

Components

noise 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).

140-Pin (11.25mm × 9mm) BGA Package

APPLICATIONS

Automotive

–

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.
