MAX1238EEE/V+T

Analog To Digital Converters (ADC) Overview

The MAX1238EEE/V+T is a low-power, 12-bit analog-to-digital converter (ADC) featuring an internal track/hold circuit, voltage reference, and clock. It operates from a single 4.5V to 5.5V supply with a maximum sampling rate of 94.4ksps. The device includes 12 analog input channels and utilizes an I2C-compatible 2-wire serial interface supporting up to 1.7MHz. It incorporates AutoShutdown technology to reduce power consumption below 1µA between conversions. The component is housed in a 16-pin QSOP package and is qualified for automotive applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm automotive qualification status. Ensure that the /V designation aligns with your project's environmental and reliability requirements before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a 12-bit resolution and 12-channel multiplexing capability are required within a 16-pin footprint. Confirm that the system operates within the specified 4.5V to 5.5V supply range and requires automotive-grade component certification.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1236–MAX1239 family of low-power, multichannel ADCs. While sharing core architecture with standard commercial variants, the /V suffix specifically denotes automotive qualification. It serves as a pin-compatible alternative to lower-resolution parts like the MAX1038 series.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX1238EEE+ for commercial grade applications. For higher resolution needs, consider the MAX1239 series, though it operates on a different supply voltage range.
