ADC14161
Low-Distortion, Self-Calibrating 14-Bit, 2.5 MSPS,
390 mW A/D Converter
General Description
The ADC14161 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 (typical).
The ADC14161 provides an easy and affordable upgrade
from 12 bit converters. The ADC14161 may also be used to
replace many hybrid converters with a resultant saving of
space, power and cost.
The ADC14161 operates with input frequencies up to 1â2 the
clock frequency. The calibration feature of the ADC14161
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 con-
versions.
Tested and guaranteed dynamic performance specifications
provide the designer with known performance.
The Power Down feature reduces power consumption to
less than 2mW.
The ADC14161 comes in a TQFP and is designed to operate
over the industrial temperature range of â40ËC to +85ËC.
