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 1⁄2 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 −40˚C to +85˚C.
