ADC12062

12-Bit 1 MHz 75 mW AD Converter

with Input Multiplexer and SampleHold

General Description

Using an innovative multistep conversion technique the

12-bit ADC12062 CMOS analog-to-digital converter digitizes

signals at a 1 MHz sampling rate while consuming a maxi-

mum of only 75 mW on a single a5V supply

The

ADC12062 performs a 12-bit conversion in three lower-res-

olution ‘‘flash’’ conversions yielding a fast AD without the

cost and power dissipation associated with true flash ap-

proaches

The analog input voltage to the ADC12062 is tracked and

held by an internal sampling circuit allowing high frequency

input signals to be accurately digitized without the need for

an external sample-and-hold circuit The multiplexer output

is available to the user in order to perform additional exter-

nal signal processing before the signal is digitized

When the converter is not digitizing signals it can be placed

in the Standby mode typical power consumption in this

mode is 100 mW
