μP Compatible 8-Bit A/D Converter
with 8-Channel Multiplexer
1
GENERAL DESCRIPTION
The ML2258 combines an 8-bit A/D converter, 8-channel
analog multiplexer, and a microprocessor compatible 8-
bit parallel interface and control logic in a single
monolithic device.
Easy interface to microprocessors is provided by the
latched and decoded multiplexer address inputs and
latched three-state outputs.
The device is suitable for a wide range of applications
from process and machine control to consumer,
automotive, and telecommunication applications.
The ML2258 is an enhanced, pin-compatible, second
source for the industry standard ADC0808/ADC0809. The
ML2258 enhancements are faster conversion time, true
sample and hold function, superior power supply
rejection, wider reference range, and a double buffered
data bus as well as faster digital timing. All parameters
are guaranteed over temperature with a power supply
voltage of 5V ±10%.
