Analog To Digital Converters (ADC) datasheet and documents for MAX1109EUB+
Analog To Digital Converters (ADC) Overview
The MAX1109EUB+ is a single-supply, low-power, 8-bit analog-to-digital converter (ADC) featuring two input channels. It operates within a supply voltage range of +4.5V to +5.5V and consumes 130µA at +5V with a 50ksps sampling rate. The device integrates an internal track/hold circuit, a clock generator, and a serial interface compatible with SPI, QSPI, and MICROWIRE protocols. It utilizes a successive-approximation architecture and includes a software-configurable power-down mode that reduces current consumption to 0.5µA. The component is housed in a compact 10-pin µMAX package.
Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes
Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the '+'' denotes compliance with RoHS standards. Ensure the 'U' designator corresponds to the 10-pin µMAX package type. Cross-reference the manufacturer's official ordering information to validate availability and exact specifications before procurement.
Analog To Digital Converters (ADC) Selection Notes
Select this component when a low-power, 8-bit resolution ADC is required for battery-operated applications. The MAX1109 variant is appropriate for systems powered by +4.5V to +5.5V supplies. Consider the integrated reference and track/hold features if external components must be minimized. Verify that the 50ksps maximum sampling rate meets the system's bandwidth requirements.
Analog To Digital Converters (ADC) Part Context
The MAX1109 is part of the MAX1108/MAX1109 family of single-supply, low-power, 2-channel, serial 8-bit ADCs. While the MAX1108 operates on +2.7V to +3.6V, the MAX1109 is specified for +4.5V to +5.5V operation. Both share identical pinouts, architectures, and feature sets, differing primarily in their operating voltage ranges and internal reference voltages.
Analog To Digital Converters (ADC) Replacement Considerations
The MAX1108CUB/EUB serves as a direct functional substitute for lower voltage applications (+2.7V to +3.6V). Other 8-bit SAR ADCs from Analog Devices may be considered if voltage ranges or channel counts differ from the MAX1109 specifications.
Analog To Digital Converters (ADC) FAQ
What is the internal reference voltage for the MAX1109?
The MAX1109 features an internal reference voltage of +4.096V.
How does the device handle power consumption during idle periods?
The device includes a software power-down mode that reduces power consumption to 0.5µA when not in use.
Can the MAX1109 operate with both single-ended and differential inputs?
Yes, the analog inputs are software configurable, allowing for unipolar/bipolar and single-ended/differential operation.
