ADC12DS105 Dual 12-Bit, 105 MSPS A/D Converter with Serial LVDS Outputs

Check for Samples: ADC12DS105

FEATURES

DESCRIPTION

The ADC12DS105 is a high-performance CMOS

analog-to-digital converter capable of converting two

analog input signals 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 uses a

differential, pipelined architecture with digital error

correction 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 differential input swing. A stable 1.2V internal

voltage reference is provided, or the ADC12DS105

can be operated with an external 1.2V reference. The

performance over a wide range of clock duty cycles.

A serial interface allows access to the internal

registers for full control of the ADC12DS105's

functionality. The ADC12DS105 is available in a 60-

lead WQFN package and operates over the industrial

temperature range of −40°C to +85°C
