MAX1111CEE+

Analog To Digital Converters (ADC) Overview

The MAX1111CEE+ is an 8-bit successive-approximation analog-to-digital converter featuring four software-configurable analog input channels. It operates from a single 2.7V to 5.5V supply and consumes 85µA at sampling rates up to 50ksps. The device integrates a track/hold circuit, a 2.048V voltage reference, and a serial interface compatible with SPI, QSPI, and MICROWIRE standards. Input configurations support unipolar or bipolar modes for both single-ended and differential signals. The component is housed in a 16-pin QSOP package and is rated for commercial temperature operation from 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal voltage reference and track/hold circuitry for simplified system design
• Software-selectable power-down mode reducing supply current to 6µA at 1ksps
• Serial interface compatible with standard microprocessor communication protocols

Analog To Digital Converters (ADC) Applications

• Portable data logging systems
• Hand-held measurement devices
• Medical instruments
• Solar-powered remote systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm the package type and temperature range. The CEE suffix indicates a commercial grade variant in a QSOP package. Confirm availability status through authorized distributors as lead times may vary based on production schedules.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-power, multichannel ADC is required for battery-operated applications. Ensure the system supports the 2.7V to 5.5V supply range and utilizes a serial interface for data transfer. Verify that the 8-bit resolution and 50ksps sampling rate meet the signal processing requirements of the target application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1110/MAX1111 family of low-power, multichannel serial ADCs. The MAX1111 variant specifically provides four analog inputs compared to the eight available in the MAX1110. Both share identical electrical characteristics, serial interface protocols, and internal architecture, differing primarily in channel count and pin configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1110EEE+ serves as a functional substitute within the same family, offering eight channels instead of four while maintaining identical electrical specifications and interface compatibility.
