ADC10080

10-Bit, 80 MSPS, 3V, 78.6 mW A/D Converter

General Description

The ADC10080 is a monolithic CMOS analog-to-digital con-

verter 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 per-

formance. 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

, with the possibility of a

single-ended input. Full use of the differential input is recom-

mended for optimum performance. An internal +1.2V preci-

sion bandgap reference is used to set the ADC full-scale

range, and also allows the user to supply a buffered refer-

enced voltage for those applications requiring increased ac-

curacy. 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.
