ADC10040 10-Bit 40 MSPS 3V, 55 mW A/D Converter November 2004 ADC10040 10-Bit, 40 MSPS, 3V, 55.5 mW A/D Converter General Description The ADC10040 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 10-bit digital words at 40 Megasamples per second (MSPS). This converter uses a differential, pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to provide a complete conversion solution, and to minimize power consumption, while providing excellent dynamic performance. A unique sample-and-hold stage yields a fullpower bandwidth of 400 MHz. Operating on a single 3.0V power supply, this device consumes just 55.5 mW at 40 MSPS, including the reference current. The Standby feature reduces power consumption to just 13.5 mW. The differential inputs provide a full scale selectable input swing of 2.0 VP-P, 1.5 VP-P, 1.0 VP-P, with the possibility of a single-ended input. Full use of the differential input is recommended for optimum performance. An internal +1.2V precision bandgap reference is used to set the ADC full-scale range, and also allows the user to supply a buffered referenced voltage for those applications requiring increased accuracy. The output data format is 10-bit offset binary, or two’s complement. This device is available in the 28-lead TSSOP package and will operate over the industrial temperature range of −40˚C to +85˚C.
