MAX1139EEE+

Analog To Digital Converters (ADC) Overview

The MAX1139EEE+ is a low-power, 10-bit analog-to-digital converter (ADC) featuring 12 analog input channels. It operates from a single supply of 2.7V to 3.6V and includes an internal track/hold circuit, voltage reference, clock, and an I²C-compatible serial interface. The device supports sampling rates up to 94.4ksps with a typical supply current of 670µA. It utilizes a successive-approximation register (SAR) architecture and is housed in a 16-pin QSOP package. The part guarantees operation over an extended temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and lead-free status. Confirm that the component meets RoHS compliance requirements for your target assembly process. Check for any recent lifecycle changes or obsolescence notices directly from Analog Devices to ensure long-term availability for production.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with 12 multiplexed channels is required in a compact surface-mount package. Ensure the system supply voltage falls within the 2.7V to 3.6V range. Verify that the I²C bus speed requirements align with the supported fast mode and high-speed mode specifications for optimal throughput performance.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1136–MAX1139 family of low-power, multichannel ADCs. It shares pin compatibility with other members of the series, such as the MAX1138, which offers similar functionality but operates at different supply voltages. The family provides options for varying channel counts and resolutions to suit diverse embedded sensing applications.

Analog To Digital Converters (ADC) Replacement Considerations

For pin-compatible alternatives with higher resolution, refer to the MAX1236–MAX1239 datasheet. For lower-resolution options, consider the MAX1036–MAX1039 series. Ensure that any substitute maintains the same 16-pin QSOP footprint and I²C interface compatibility.
