ADC12062
12-Bit, 1 MHz, 75 mW A/D Converter
with Input Multiplexer and Sample/Hold
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
a
5V supply. The
ADC12062 performs a 12-bit conversion in three lower-res-
olution ‘‘flash’’ conversions, yielding a fast A/D 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
m
W.
