1 / 23 page  ADC12L080 12-Bit, 80 MSPS, 450 MHz Bandwidth A/D Converter with Internal Reference General Description The ADC12L080 is a monolithic CMOS analog-to-digital con- verter 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 con- sumes just 425 mW at 80 MSPS, including the reference current. The Power Down feature reduces power consump- tion to just 50 mW. The differential inputs provide a full scale input swing equal to ±V REF. 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 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.
