ML2258*  
µP Compatible 8-Bit A/D Converter  
with 8-Channel Multiplexer  
GENERAL DESCRIPTION  
FEATURES  
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.  
Conversion time  
Total unadjusted error  
No missing codes  
Sample and hold  
6.6µs  
±1/2LSB or ±1LSB  
390ns acquisition  
Easy interface to microprocessors is provided by the  
latched and decoded multiplexer address inputs and  
latched three-state outputs.  
Capable of digitizing a 5V, 50kHz sine wave  
8-input multiplexer  
The device is suitable for a wide range of applications  
from process and machine control to consumer,  
automotive, and telecommunication applications.  
0V to 5V analog input range with single 5V  
power supply  
Operates ratiometrically or with up to 5V  
voltage reference  
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%.  
No zero-or full-scale adjust required  
Analog input protection  
Low power dissipation  
25mA per input min  
3mA max  
TTL and CMOS compatible digital inputs and outputs  
Standard 28-pin DIP or surface mount PCC  
Superior pin compatible replacement for ADC0808 and  
ADC0809  
* Some Packages Are End Of Life As Of August 1, 2000
