8-Bit CODECs  
General Description  
Features  
The MAX1102/MAX1103/MAX1104 CODECs provide  
both an 8-bit analog-to-digital converter (ADC) and an  
8-bit digital-to-analog converter (DAC) with a 4-wire  
logic interface. The MAX1102/MAX1103 include an  
onboard +2V/+4V reference, providing a well-regulat-  
ed, low noise reference for both the ADC and DAC.  
The MAX1104 offers ratiometric conversion, with the

o ꢀnternal Conversion Clock  
The MAX1102/MAX1103/MAX1104 are low-cost, low-  
power CODECs for use with microcontrollers (µCs).  
They allow for greater flexibility when selecting a µC.  
Less expensive µCs without onboard converters can be  
used while maintaining overall system performance.  
o Lingle-Lupply Operation  
+2.7V to +3.6V (MAX±±02)  
+4.5V to +5.5V (MAX±±03)  
+2.7V to +5.5V (MAX±±04)  
o 1ow Power Consumption  
0.5mA at 25ksps  
The MAX1102 operates from a single +2.7V to +3.6V  
supply, the MAX1103 operates from a +4.5V to +5.5V  
supply, and the MAX1104 operates from a +2.7V to  
+5.5V supply. The MAX1102/MAX1103 incorporate a  
±µA Lhutdown Mode

toring. All devices feature a low 18µA standby mode,  
where both data converters are disabled while the ref-  
erence remains active, and three shutdown modes:  
ADC disabled, DAC disabled, and complete shutdown  
(1µA). A quick 10µs wake-up time allows the  
MAX1102/MAX1103/MAX1104 to cycle in and out of  
shutdown even during short-duration idle times.  
o Compact 8-Pin µMAX Package  
o ꢀnternal Voltage Reference  
+2V: MAX±±02  
+4V: MAX±±03  
o Power-Lupply Monitor (MAX±±02/MAX±±03)  
o Rail-to-Rail® DAC Output Buffer  
The MAX1102/MAX1103/MAX1104 are available in a  
space-saving 8-pin µMAX package.
