The ADC12040 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 40 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 340 mW at 40 MSPS, including the reference current. The Power Down feature reduces power consumption to 40 mW.

The differential inputs provide a full scale differential input swing equal to 2VREF with the possibility of a single-ended input, although full use of the differential input is required 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.
