ADC10065
10-Bit 65 MSPS 3V A/D Converter
General Description
The ADC10065 is a monolithic CMOS analog-to-digital con-
verter 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 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 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 V

, 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 40C to
+85C.
