描述 Description

The ADC10080 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 10-bit digital words at 80 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 full-power bandwidth of 400 MHz. Operating on a single 3.0V power supply, this device consumes just 78.6 mW at 80 MSPS, including the reference current. The Standby feature reduces power consumption to just 15 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 user choice of 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.
