MAX1238MEEE+

Analog To Digital Converters (ADC) Overview

The MAX1238MEEE+ is a low-power, 12-bit analog-to-digital converter (ADC) featuring 12 analog input channels. It operates from a single supply voltage of 4.5V to 5.5V and includes an internal track/hold circuit, clock generator, and a 4.096V internal voltage reference. The device utilizes an I²C-compatible 2-wire serial interface supporting data rates up to 1.7MHz in high-speed mode. It achieves a maximum sampling rate of 94.4ksps with a typical supply current of 670µA. The part is housed in a 16-pin QSOP package and is guaranteed to operate over an extended temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-channel analog multiplexer with software-configurable unipolar or bipolar operation modes.
• Features AutoShutdown technology that powers down the device between conversions to minimize power consumption.
• Supports both internal and external reference voltages ranging from 1V to VDD for flexible system design.

Analog To Digital Converters (ADC) Applications

• Handheld portable applications
• Medical instruments
• Battery-powered test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and lead-free status. Ensure the supply voltage requirements align with the 4.5V to 5.5V operational range specified for this variant. Confirm availability through authorized distributors as stock levels fluctuate.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and multi-channel acquisition are required within a low-power constraint. Compare against the MAX1236 for lower channel counts or the MAX1239 if a lower supply voltage range is necessary. Verify that the I²C bus timing meets the system's high-speed mode requirements for optimal throughput.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX1236–MAX1239 family of low-power, multichannel ADCs. It shares architectural similarities with the MAX1236, MAX1237, and MAX1239, differing primarily in channel count and supply voltage specifications. Pin-compatible 10-bit and 8-bit alternatives exist within the MAX1136–MAX1139 and MAX1036–MAX1039 series respectively.
