MAX1039LEEE

Analog To Digital Converters (ADC) Overview

The MAX1039LEEE+ is an 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single power supply ranging from 2.7V to 5.5V and supports up to 12 input channels in either pseudo-differential or single-ended configurations. The device features an I2C-compatible serial interface, allowing for simplified system integration. Key electrical specifications include a sampling rate of 188 kS/s, a signal-to-noise ratio (SNR) of 49 dB, and integral/differential nonlinearity errors limited to ±1 LSB. It is housed in a 16-lead QSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'L' against official Analog Devices documentation to confirm voltage ranges and pinout compatibility, as variations exist within the MAX1039 family. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Check availability status directly with authorized distributors, as lead times may vary based on production cycles.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy requirements. Ensure the system design accommodates the I2C bus speed limitations at the maximum sampling rate. Verify that the input signal range aligns with the internal reference voltage capabilities or external reference requirements specified in the electrical characteristics table.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1039A series of low-power, multi-channel ADCs. It shares architectural similarities with the MAX1238 and MAX1239 series but differs in resolution (8-bit vs. 12-bit) and input configuration options. The MAX1039LEEE variant specifically targets applications balancing channel count, speed, and power efficiency in compact surface-mount packages.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the MAX1039AEEE+ for identical functionality. For higher resolution needs, consider the MAX1238LEEE+ or MAX1239LEEE+, noting the change in bit depth and potential impact on sampling rates. Cross-reference pinouts and software compatibility before implementing any alternative.
