DESCRIPTION

The ADC12L080 is a monolithic CMOS analog-to- digital converter capable of converting analog input

signals into 12-bit digital words at 80 Megasamples

per second (MSPS). This converter uses a

differential, pipeline architecture with digital error

correction and an on-chip sample-and-hold circuit to minimize die size and power consumption while

providing excellent dynamic performance. The

ADC12L080 can be operated with either the internal

or an external reference. Operating on a single 3.3V

power supply, this device consumes just 425 mW at

80 MSPS, including the reference current. The Power

Down feature reduces power consumption to just 50

mW.

The differential inputs provide a full scale input swing

equal to ±VREF. The buffered, high impedance, single•

ended external reference input is converted on-chip

to a differential reference for use by the processing

circuitry. Output data format may be selected as

either offset binary or two's complement.

This device is available in the 32-lead LQFP package

and operates over the industrial temperature range of

−40°C to +85°C.
