and Input Multiplexer
General Description
Using a patented multi-step A D conversion technique the
8-bit ADC08061 and ADC08062 CMOS ADCs offer 500 ns
(typ) conversion time internal sample-and-hold (S H) and
dissipate only 125 mW of power The ADC08062 has a two-
channel multiplexer The ADC08061 2 family performs an
8-bit conversion using a 2-bit voltage estimator that gener-
ates the 2 MSBs and two low-resolution (3-bit) flashes that
generate the 6 LSBs
Input track-and-hold circuitry eliminates the need for an ex-
ternal sample-and-hold The ADC08061 2 family performs
accurate conversions of full-scale input signals that have a
frequency range of DC to 300 kHz (full-power bandwidth)
without need of an external S H
The digital interface has been designed to ease connection
to microprocessors and allows the parts to be I O or memo-
ry mapped
