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 1â2 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 0ËC to +70ËC.
