ADC14061
Self-Calibrating 14-Bit, 2.5 MSPS, 390 mW A/D Converter
General Description
The ADC14061 is a self-calibrating 14-bit, 2.5 Megasample
per second analog to digital converter. It operates on a single
+5V supply, consuming just 390mW (typ).
The ADC14061 provides an easy and affordable upgrade
from 12 bit converters. The ADC14061 may also be used to
replace many hybrid converters with a resultant saving of
space, power and cost.
The ADC14061 operates with excellent dynamic perfor-
mance at input frequencies up to
1 ⁄
2
the clock frequency. The
calibration feature of the ADC14061 can be used to get more
consistent and repeatable results over the entire operating
temperature range. On-command self-calibration reduces
many of the effects of temperature-induced drift, resulting in
more repeatable conversions.
The Power Down feature reduces power consumption to
less than 2mW.
The ADC14061 comes in a TQFP and is designed to operate
over the commercial temperature range of 0˚C to +70˚C.
