MAX1111EPE+

Analog To Digital Converters (ADC) Overview

The MAX1111EPE+ is an 8-bit successive-approximation analog-to-digital converter (ADC) housed in a 16-pin QSOP package. It operates from a single 2.7V to 5.5V supply and features four software-configurable analog inputs supporting unipolar/bipolar and single-ended/differential modes. The device integrates a track/hold circuit, a 2.048V internal reference, and a clock, consuming 85µA at sampling rates up to 50ksps. It supports SPI, QSPI, and MICROWIRE serial interfaces with a software-programmable power-down mode reducing current to 6µA.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a track/hold circuit, voltage reference, and clock for standalone operation
• Supports SPI, QSPI, and MICROWIRE compatible serial interfaces
• Features software-configurable unipolar or bipolar input ranges
• Includes a programmable automatic power-down mode for low-power applications

Analog To Digital Converters (ADC) Applications

• Portable data logging systems
• Hand-held measurement devices
• Medical instruments
• Solar-powered remote systems
• 4mA to 20mA-powered remote data-acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix EPE against official documentation to confirm the industrial temperature range (-40°C to +85°C) and QSOP package type. Ensure the ordering code matches the exact pin configuration and electrical specifications required for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with multichannel capability is required for low-power designs. Consider the MAX1110 if eight single-ended channels are needed instead of four. Evaluate the source impedance requirements, as high impedance may necessitate longer acquisition times to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1110/MAX1111 family of low-power, multichannel, serial 8-bit ADCs manufactured by Analog Devices Inc./Maxim Integrated. The MAX1111 variant specifically provides four configurable analog inputs, distinguishing it from the eight-channel MAX1110 model within the same series.

Analog To Digital Converters (ADC) Replacement Considerations

MAX1110EEE+ offers identical electrical characteristics but includes eight analog input channels instead of four. Verify channel count requirements before substitution.
