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 conversions. 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 to +85.
