MAX8069ESA+T

Overview

The MAX8069ESA+T is a low-voltage, temperature-compensated bandgap voltage reference manufactured by Analog Devices Inc. (Maxim Integrated). It provides a nominal output of 1.2V with a maximum temperature coefficient of 25ppm/°C over the -40°C to +85°C industrial range. The device operates at reverse currents as low as 60µA and features low dynamic impedance and RMS noise of 20µV (10Hz to 10kHz). Packaged in an 8-pin SOIC, it serves as a functional alternative to the ICL8069.

Feature Summary

• Temperature-compensated bandgap design ensures excellent stability and freedom from oscillation
• Operates effectively at very low reverse bias currents down to 60µA
• Features low dynamic impedance and low RMS noise for precision applications
• Identical pinout to Maxim’s legacy ICL8069 component

Applications

• Analog-to-Digital Converters
• Digital-to-Analog Converters
• Threshold Detectors
• Voltage Regulators
• Portable Instruments

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated. Ensure the part number includes the lead-free indicator (+) if RoHS compliance is required. Cross-reference the SOIC-8 package code S8-2 against current distributor catalogs to ensure physical compatibility.

Selection Notes

Select this component when a stable 1.2V reference is needed in space-constrained designs using the SOIC-8 package. It is suitable for replacing older ICL8069 units without PCB layout changes. Consider the 25ppm/°C tempco limit for environments exceeding standard room temperature ranges. Verify that the system can support the minimum 60µA reverse current requirement for proper regulation.

Part Context

This part belongs to the MAX8069 series of low-voltage references. The 'ESA' designation specifies the -40°C to +85°C operating temperature range and the SOIC-8 surface-mount package. The '+T' suffix typically denotes reel packaging for automated assembly. The series is designed to offer cost-effective precision referencing for portable and battery-powered instrumentation.

Replacement Considerations

The datasheet explicitly identifies the MAX8069 as a functional alternative to the Maxim ICL8069 with an identical pinout. No other substitute part numbers are documented in the provided source material.
