MAX1037MEKA+T

Analog To Digital Converters (ADC) Overview

The MAX1037MEKA+T is an 8-bit, low-power analog-to-digital converter (ADC) featuring four analog input channels. It operates from a single 2.7V to 3.6V supply and integrates a track/hold circuit, internal clock, and a 2.048V voltage reference. The device utilizes a high-speed I²C-compatible 2-wire serial interface supporting up to 1.7MHz. Power consumption is 350µA at the maximum sampling rate of 188ksps, reducing to less than 1µA in AutoShutdown mode. It is housed in an 8-pin SOT23 package and guaranteed for operation over the extended industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Four-channel architecture with software-configurable unipolar or bipolar single-ended/pseudo-differential inputs
• Integrated 2.048V internal reference with support for external references from 1V to VDD
• High-speed I²C-compatible serial interface operating at 400kHz (Fast Mode) or 1.7MHz (High-Speed Mode)
• AutoShutdown technology reduces supply current to under 1µA between conversions

Analog To Digital Converters (ADC) Applications

• Handheld portable applications
• Medical instruments
• Battery-powered test equipment
• Solar-powered remote systems
• Received-signal-strength indicators

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component corresponds to the specific ordering suffix MEKA+T, which indicates the 8-pin SOT23 package variant. Confirm compliance with RoHS standards as indicated by the plus sign in the part number. Ensure the supply voltage requirements align with the 2.7V to 3.6V specification for this specific model within the MAX1036–MAX1039 family.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1037MEKA+T when four analog input channels are required with an integrated 2.048V reference. This model is suitable for designs constrained by a 2.7V to 3.6V power supply. For applications requiring twelve channels or a 4.096V internal reference, consider the MAX1038 or MAX1036 variants respectively. Ensure the system supports the necessary I²C timing modes for the desired throughput rate.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1036–MAX1039 family of low-power, multichannel ADCs. While sharing the same core architecture and interface, the MAX1037 differs from the MAX1036/MAX1038 by its lower voltage requirement (2.7V–3.6V vs. 4.5V–5.5V) and its specific 2.048V internal reference voltage. It shares the 8-pin SOT23 package form factor with the MAX1036.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1036EKA+T serves as a functional substitute within the same package but requires a 4.5V to 5.5V supply and features a 4.096V internal reference. Higher resolution alternatives include the MAX1136–MAX1139 series for 10-bit performance and the MAX1236–MAX1239 series for 12-bit performance.
