71M6601-ILR/F

Overview

The 71M6601-ILR/F is a single-channel isolated sensor interface IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates a sigma-delta analog-to-digital converter (ADC) designed for precision measurement applications. The device operates within a supply voltage range of 2.4 V to 5.5 V and draws a typical operating current of 250 uA. It supports differential input signals and is housed in an SOIC-8 surface-mount package. The component functions reliably across an industrial temperature range from -40 C to +85 C, ensuring stable performance in demanding environments.

Feature Summary

• Integrates a sigma-delta ADC for high-resolution signal conversion
• Provides galvanic isolation for sensor interface applications
• Supports differential input configurations for noise rejection

Applications

• Isolated sensor signal conditioning
• Industrial process control monitoring
• Precision measurement systems

Procurement Notes

Verify the specific suffix ILR/F against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Ensure the source is an authorized distributor or Analog Devices directly to guarantee authenticity. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations.

Selection Notes

Select this component when designing circuits requiring isolated data acquisition from sensors. The sigma-delta architecture offers high resolution suitable for precision tasks. Verify that the required input signal range matches the device capabilities. Consider the SOIC-8 footprint constraints during PCB layout. Ensure the operating temperature range aligns with the intended application environment.

Part Context

This part belongs to the 71M series of energy metering and sensor interface products from Maxim Integrated, now part of Analog Devices. These devices are typically used in utility metering and industrial instrumentation. The 71M6601 variant specifically focuses on isolated sensor interfaces rather than direct energy metering, expanding the family's utility in broader measurement scenarios.
