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 V_P-P, 1.5 V_P-P, 1.0 V_P-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.
