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).

Features

n Single +5V Operation

n Auto-Calibration

n Power Down Mode

n TTL/CMOS Input/Output compatible

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.

Key Specifications

n Resolution

14 Bits

2.5 Msps (min)

0.3 LSB (typ)

80 dB (typ)

The ADC14061 operates with excellent dynamic perfor-

mance at input frequencies up to ¹⁄

the clock frequency. The

n DNL

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.

n SNR (f_IN= 500 kHz)

n ENOB

12.8 Bits (typ)

n Supply Voltage

n Power Consumption

+5V

The Power Down feature reduces power consumption to

less than 2mW.

390mW (typ)

The ADC14061 comes in a TQFP and is designed to operate

over the commercial temperature range of 0˚C to +70˚C.

Applications

n Instrumentation

n PC-Based Data Acquisition

n Data Communications

n Blood Analyzers

n Sonar/Radar
