描述 Description

The ADC12010 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 10 Megasamples per second (MSPS), minimum. 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. Operating on a single 5V power supply, this device consumes just 160 mW at 10 MSPS, including the reference current. The Power Down feature reduces power consumption to 25 mW.The differential inputs provide a full scale input swing equal to 2VREF with the possibility of a single-ended input. Full use of the differential input is recommended 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.
