ADC12040 - National Semiconductor

ADC12040 12-Bit/ 40 MSPS/ 340 mW A/D Converter

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 providi.
