ADC12L080

The ADC12L080 is a monolithic CMOS analog-to-digital con-verter capable of converting analog input signals into 12-bit digital words at 80 Megasamplesper second(MSPS). This converter uses a differential, pipe line architecture with digital error correction and anon-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 con-sumes just 425mW at 80MSPS, including the reference current.The Power Down feature reduces power consump-tion to just 50mW.

The differential inputs provide a full scale input swing equal to ± VREF.The buffered, high impedance,single-ended ex-ternal reference input is converted on-chip to a differential reference for use by the processing circuitry. Output data format maybe select edaseither offset binary or two'scomplement.

This device is available in the 32-lead LQFP package and operates over the industrial temperature range of −40˚C to +85˚C.
