DESCRIPTION

The ADC10065 is a monolithic CMOS analog-to-

digital converter capable of converting analog input

signals into 10-bit digital words at 65 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 68.4 mW at 65 MSPS,

including the reference current. The Standby feature

reduces power consumption to just 14.1 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.
