ADC14DS080

Dual 14-Bit, 80 MSPS A/D Converter with Serial LVDS

Outputs

General Description

Features

The ADC14DS080 is a high-performance CMOS analog-to-

digital converter capable of converting two analog input sig-

nals into 14-bit digital words at rates up to 80 Mega Samples

Per Second (MSPS). The digital outputs are serialized and

provided on differential LVDS signal pairs. These converters

use a differential, pipelined architecture with digital error cor-

rection and an on-chip sample-and-hold circuit to minimize

power consumption and the external component count, while

providing excellent dynamic performance. A unique sample-

and-hold stage yields a full-power bandwidth of 1 GHz. The

ADC14DS080 may be operated from a single +3.0V or 3.3V

power supply. A power-down feature reduces the power con-

sumption to very low levels while still allowing fast wake-up

time to full operation. The differential inputs accept a 2V full

scale differential input swing. A stable 1.2V internal voltage

reference is provided, or the ADC14DS080 can be operated

with an external 1.2V reference. Output data format (offset

binary versus 2's complement) and duty cycle stabilizer are

selectable. The duty cycle stabilizer maintains performance

over a wide range of clock duty cycles. A serial interface al-

lows access to the control registers for full control of the

ADC14DS80 functionality. The ADC14DS080 is available in

a 60-lead LLP package and operates over the industrial tem-

perature range of −40°C to +85°C.
