DESCRIPTION

The ADC14DS080 is a high-performance CMOS

analog-to-digital converter capable of converting two

analog input signals 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

correction 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

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

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 allows access to the control

registers for full control of the ADC14DS80

functionality. The ADC14DS080 is available in a 60-

lead WQFN package and operates over the industrial

temperature range of −40°C to +85°C.
