ADC14071

14-Bit, 7 MSPS, 380 mW A/D Converter

General Description

Features

n Single +5V Operation

n Power Down Mode

The ADC14071 is a 14-bit, monotholic analog to digital con-

verter capable of conversion rates up to 8 Megasamples per

second. This CMOS converter uses a differential, piperlined

architecture with digital error correction and an on-chip

track-and-hold circuit to maintain superb dynamic perfor-

mance with input frequencies up to 20MHz. Tested and guar-

anteed dynamic performance specifications provide the de-

signer with known performance. The ADC14071 operates on

a +5V single supply consuming just 380mW (typical). The

Power Down feature reduces power consumption to 20mW,

typical.

n TTL/CMOS Input/Output Compatible

Key Specifications

n Max Conversion Rate

n DNL

14 Bits

7 Msps (min)

0.6 LSB (typ)

80 dB (typ)

n SNR (f_IN500 kHz)

n ENOB (f_W= 500 kHz)

n Supply Voltage

12.6 Bits (typ)

The differential inputs provide a full scale input swing of

+5V 5%

V_REFwith the possibility of a single input. Full use of the dif-

n Power Consumption

380 mW (typ)

ferential input is recommended for optimum perfomance. For

ease of use, the reference input is single ended. This single-

ended reference input is converted on-chip to a differential

reference configuration for use by the processing circuitry.

Output data format is 14-bit straight binary.

Applications

n Document Scanners

n Imaging

n Instrumentation

n PC-Based Data Acquisition

n Spectrum Analyzers

n Sonar/Radar

The ADC14071 may be used to replace many hybrid con-

verters with a resultant saving of space, power and cost.

The ADC14071 comes in a 48-pin TQFP and is specified to

operate over the industrial temperature range of −40˚C to

+85˚C.
