MAX11614EEE+

Analog To Digital Converters (ADC) Overview

The MAX11614EEE+ is a low-power, 12-bit analog-to-digital converter (ADC) featuring an I²C-compatible serial interface. It operates from a single supply of 4.5V to 5.5V and includes an internal track/hold circuit, voltage reference, and clock. The device provides eight analog input channels and supports sampling rates up to 94.4ksps with a typical supply current of 670µA. It utilizes successive-approximation architecture and offers software-configurable unipolar or bipolar input ranges.

• Battery-powered test equipment
• Solar-powered remote systems
• Received-signal-strength indicators

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure the system power supply aligns with the required 4.5V to 5.5V operating voltage. Confirm that the I²C bus timing meets the specified Fast Mode or High-Speed Mode requirements for reliable data transfer.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and multi-channel capability are required in a compact form factor. The MAX11614EEE+ is suitable for designs needing an integrated reference and clock to minimize external components. Consider the 16-pin QSOP package constraints and the specific 4.5V to 5.5V supply requirement compared to lower-voltage variants in the series.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11612–MAX11617 family of low-power, multi-channel ADCs. While sharing similar architectures, members of this series differ in channel count and supply voltage ranges. The MAX11614 variant specifically provides eight channels and requires a higher supply voltage compared to the MAX11613/MAX11615 counterparts.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include other devices within the MAX11612–MAX11617 series, such as the MAX11615EEE+, provided the supply voltage and channel configuration requirements are met. Verify that any substitute maintains the same I²C slave address if multiple devices share the bus.
