ADC12L063 Datasheet | National Semiconductor

Description The ADC12L063 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 62 Megasamples per second (MSPS), minimum. This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-andhold circuit to minimize die size and power consumption while providing excellent dynamic performance. Operating on a single 3.3V power supply, this device consumes just 354 m W at 62 MSPS, including the reference current. The Power Down feature reduces power consumption to just 50 m W. The differential inputs provide a full scale input swing equal to ± VREF with the possibility of a single-ended input. Full use of the differential input is remended for optimum performance. For ease of use, the buffered, high impedance, single-ended reference input is converted on-chip to a differential reference for use by the processing circuitry. Output data format is 12-bit offset binary. This device is available in the 32-lead LQFP package and will operate over the industrial temperature range of - 40˚C to +85˚C.
