MAX1115EKA+T

Analog To Digital Converters (ADC) Overview

The MAX1115EKA+T is a single-supply, low-power, serial 8-bit analog-to-digital converter (ADC) from the MAX1115/MAX1116 family. It integrates an internal track/hold circuit, voltage reference, VDD monitor, clock, and serial interface within an 8-pin SOT23 package. The device operates on a supply voltage ranging from +2.7V to +5.5V and supports sampling rates up to 100ksps using its internal clock. It features a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Power consumption is specified at 175µA during operation at 100ksps, reducing to less than 1µA in AutoShutdown power-down mode.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal track/hold circuit, voltage reference, and clock for simplified system design
• Features a 3-wire serial interface directly compatible with SPI, QSPI, and MICROWIRE devices without external logic
• Includes an automatic power-down mode that significantly reduces current consumption when idle

Analog To Digital Converters (ADC) Applications

• Low-Power, Hand-Held Portable Devices
• System Diagnostics
• Battery-Powered Test Equipment
• Receive-Signal-Strength Indicators
• 4mA to 20mA Powered Remote Data-Acquisition Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm the specific ordering suffix matches the required temperature range and package type. Ensure the source provides valid traceability records. Cross-reference the part number with the manufacturer's latest datasheet to confirm specifications before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring an 8-bit resolution ADC with minimal external components. It is suitable for battery-powered systems due to its low active and shutdown currents. Ensure the input signal range aligns with the internal 2.048V reference. Verify that the host microcontroller supports the required 3-wire serial communication protocol.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1115/MAX1116 series of single-supply, low-power, serial 8-bit ADCs manufactured by Analog Devices / Maxim Integrated. The EKA suffix indicates an 8-pin SOT23 package with an operating temperature range of -40°C to +85°C. The '+' suffix denotes compliance with lead-free manufacturing standards.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX1116EKA+T is a direct functional substitute within the same series, differing primarily in its specified supply voltage range of +4.5V to +5.5V compared to the MAX1115's +2.7V to +5.5V range.
