1 / 30 page ADC12040 www.ti.com SNAS135G – FEBRUARY 2001 – REVISED MARCH 2013 ADC12040 12-Bit, 40 MSPS, 340mW A/D Converter with Internal Sample-and-Hold Check for Samples: ADC12040 1 FEATURES DESCRIPTION The ADC12040 is a monolithic CMOS analog-to- 2 • Single +5V Supply Operation digital converter capable of converting analog input • Internal Sample-and-Hold signals into 12-bit digital words at 40 Megasamples • Outputs 2.35V to 5V Compatible per second (MSPS), minimum. This converter uses a differential, pipeline architecture with digital error • Pin Compatible with ADC12010, ADC12020, correction and an on-chip sample-and-hold circuit to ADC12L063, ADC12L066 minimize die size and power consumption while • Power Down Mode providing excellent dynamic performance. Operating • On-Chip Reference Buffer 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 APPLICATIONS consumption to 40 mW. • Ultrasound and Imaging The differential inputs provide a full scale differential • Instrumentation input swing equal to 2VREF with the possibility of a • Cellular Base Stations/Communications single-ended input, although full use of the differential Receivers input is required for optimum performance. For ease of use, the buffered, high impedance, single-ended • Sonar/Radar reference input is converted on-chip to a differential • xDSL reference for use by the processing circuitry. Output • Wireless Local Loops/Cable Modems data format is 12-bit offset binary. • HDTV/DTV This device is available in the 32-lead LQFP package • DSP Front Ends and will operate over the industrial temperature range of −40°C to +85°C. KEY SPECIFICATIONS • Supply Voltage: +5V ±5% • DNL: ±0.4 LSB (typ) • SNR (fIN = 10MHz): 69 dB (typ) • ENOB (fIN = 10MHz): 11.2 bits (typ) • Power Consumption, 40 MHz: 340 mW (typ) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
