ADC14061 Self-Calibrating 14-Bit, 2.5 MSPS, 390 mW A/D Converter January 2000 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 performance at input frequencies up to 1⁄2 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 0˚C to +70˚C.
