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

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

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 −40˚C to +85˚C.
