MAX6164AESA+ Equivalent & Substitute Parts

Part Overview

The MAX6164AESA+ is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated, delivering a fixed 4.096V output with ±0.05% tolerance. This component operates as a precision voltage reference in power management applications, housed in an 8-SOIC surface mount package. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements permit relaxed tolerance specifications, extended operating temperature ranges, or alternative packaging formats while maintaining the same output voltage, package footprint, and core functionality.

Variable Parameters (Permit Substitution):

Tolerance: ±0.05% or wider (±0.07%, ±0.1%, ±0.15%)
Temperature coefficient: 5ppm/°C or higher
Input voltage range: 4.296V ~ 12.6V or wider (5V ~ 15V)
Supply current: 120µA or lower (18µA represents improvement)
Operating temperature: -40°C ~ 85°C or extended range (-40°C ~ 125°C)

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the MAX6164AESA+. Selection between substitute options depends on application tolerance requirements:

ADR292ERZ / ADR292ERZ-REEL: Select when ±0.07% tolerance is acceptable. These parts offer improved supply current efficiency (18µA vs. 120µA) and extended operating temperature range (-40°C ~ 125°C). ADR292ERZ-REEL provides Tape & Reel packaging for automated assembly.

ADR292FRZ / ADR292FRZ-REEL7: Select when ±0.1% tolerance is acceptable. Maintains same advantages as ADR292ERZ series with relaxed tolerance specification. ADR292FRZ-REEL7 provides Tape & Reel format.

ADR292GRZ / ADR292GRZ-REEL7: Select when ±0.15% tolerance is acceptable. Offers maximum tolerance relaxation while retaining core functionality. ADR292GRZ-REEL7 provides Cut Tape & Digi-Reel® packaging with highest inventory availability (80,433 units).

All ADR292 variants operate across -40°C ~ 125°C, providing 40°C extended upper temperature range compared to MAX6164AESA+ (-40°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can ADR292 series parts directly replace MAX6164AESA+ in existing designs?

A: Direct replacement is possible when application tolerance specifications permit relaxation from ±0.05% to ±0.07%, ±0.1%, or ±0.15%. The 8-SOIC package footprint is identical, and output voltage (4.096V) and current (5 mA) are unchanged. Verify tolerance requirements before substitution.

Q: What is the primary difference between MAX6164AESA+ and ADR292 variants?

A: The MAX6164AESA+ specifies ±0.05% tolerance with 5ppm/°C temperature coefficient and operates to 85°C. ADR292 variants offer wider tolerance specifications (±0.07% to ±0.15%), higher temperature coefficients (8ppm/°C to 25ppm/°C), extended operating range to 125°C, and significantly lower supply current (18µA vs. 120µA).

Q: Does packaging format affect electrical performance?

A: No. Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel® packaging formats contain identical die and electrical specifications. Format selection is driven by assembly process requirements and volume handling.

Q: Which ADR292 variant offers the best inventory availability?

A: ADR292GRZ-REEL7 provides the highest stock level (80,433 units) with Cut Tape & Digi-Reel® packaging. This variant accepts ±0.15% tolerance and operates across -40°C ~ 125°C.

Q: Is input voltage range compatibility a concern when substituting?

A: The MAX6164AESA+ accepts 4.296V ~ 12.6V input. ADR292 variants accept 5V ~ 15V input, which is a wider range. Designs operating below 5V input require MAX6164AESA+ or verification that ADR292 minimum input specification (5V) is met.
