MAX6160EUS

Overview

The MAX6160EUS is a precision, low-dropout, micropower three-terminal voltage reference housed in a 4-pin SOT-143 surface-mount package. It operates with an input voltage range from (V_OUT + 200mV) to 12.6V and draws a typical supply current of 75µA, independent of input voltage. The device features a proprietary curvature-correction circuit and laser-trimmed thin-film resistors, achieving a maximum temperature coefficient of 5ppm/°C and an initial accuracy of ±2mV. Specifications are valid across the extended industrial temperature range of -40°C to +85°C.

Feature Summary

• Proprietary curvature-correction circuitry ensures high stability over temperature variations
• Laser-trimmed thin-film resistors provide precise initial accuracy without external adjustment
• Micropower operation maintains constant 75µA supply current regardless of input voltage changes
• Low dropout capability allows efficient regulation with minimal headroom requirements

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered systems optimizing for low quiescent current
• Data acquisition systems needing high precision analog references
• Industrial control circuits operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'EUS' confirms the SOT-143-4 package and adjustable output variant. Confirm the '+T' designation if tape-and-reel packaging is required for automated assembly. Ensure the manufacturer is identified as Analog Devices Inc. or Maxim Integrated to guarantee component authenticity and datasheet alignment. Check for RoHS compliance markings on the reel or shipping documentation.

Selection Notes

Select this component when a compact SOT-143 footprint is necessary alongside micropower efficiency. It is suitable for applications where input voltage varies but must remain above V_OUT + 200mV. Choose this part over larger packages if board space is constrained. Consider the adjustable output range if fixed voltage options do not match system requirements exactly.

Part Context

The MAX6160 belongs to the broader MAX616x family of precision voltage references, which includes variants like the MAX6161 through MAX6168. While other family members may offer fixed output voltages or different packages such as SO-8, the MAX6160 specifically provides an adjustable output option within the SOT-143 form factor. This series shares common technologies like curvature correction and low dropout design principles.

Replacement Considerations

Direct substitutes include other MAX616x series devices with compatible pinouts or electrical characteristics, such as the MAX6161ESA for fixed voltage needs in an SO-8 package. Verify that any replacement maintains the 75µA supply current and 5ppm/°C temperature coefficient specifications to ensure circuit performance parity.
