ADC12DS105

Dual 12-Bit, 105 MSPS A/D Converter with Serial LVDS

Outputs

General Description

Features

The ADC12DS105 is a high-performance CMOS analog-to-

digital converter capable of converting two analog input sig-

nals into 12-bit digital words at rates up to 105 Mega Samples

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

provided on differential LVDS signal pairs. This converter us-

es 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. The ADC12DS105

may be operated from a single +3.0V or 3.3V power supply.

A power-down feature reduces the power consumption to

very low levels while still allowing fast wake-up time to full

operation. The differential inputs accept a 2V full scale differ-

ential input swing. A stable 1.2V internal voltage reference is

provided, or the ADC12DS105 can be operated with an ex-

ternal 1.2V reference. The selectable duty cycle stabilizer

maintains performance over a wide range of clock duty cy-

cles. A serial interface allows access to the internal registers

for full control of the ADC12DS105's functionality. The AD-

C12DS105 is available in a 60-lead LLP package and oper-

ates over the industrial temperature range of −40°C to +85°C
