Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX6164BESA is determined by strict equivalence across the following critical parameters:

Fixed Substitution Criteria:

• Output voltage: 4.096V (fixed)
• Output current capability: 5 mA minimum
• Package type: 8-SOIC form factor
• Mounting type: Surface mount
• Reference type: Series voltage reference

Tolerance and Performance Considerations: Substitute parts are grouped by tolerance specification (±0.07%, ±0.1%, ±0.12%, ±0.15%), which directly impacts circuit accuracy. The MAX6164BESA operates at ±0.12% tolerance; substitutes with equal or tighter tolerance specifications maintain or improve performance. Parts with looser tolerance (±0.15%) represent functional alternatives where circuit design permits relaxed accuracy requirements.

Temperature Range and Supply Current: The MAX6164BESA operates from -40°C to 85°C with 120µA supply current. Substitute parts from the ADR292 series extend the operating range to -40°C to 125°C and reduce supply current to 18µA, providing enhanced performance margins. These improvements do not compromise compatibility.

Compliance Status: The MAX6164BESA is RoHS non-compliant and obsolete. Active substitute parts (MAX6164BESA+, ADR292 series) carry ROHS3 compliance and active product status, supporting long-term availability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Specifications): MAX6164BESA+ is the direct active equivalent, maintaining identical electrical specifications (±0.12% tolerance, 10ppm/°C temperature coefficient, 120µA supply current) while transitioning from obsolete to active product status. This part carries ROHS3 compliance and is available in tube packaging. Selection of MAX6164BESA+ is appropriate for designs requiring no performance modification and immediate compliance upgrade.

Performance-Enhanced Substitutes (ADR292 Series): The ADR292 series represents manufacturer-recommended alternatives offering superior performance characteristics across multiple parameters. ADR292ERZ and ADR292ERZ-REEL deliver ±0.07% tolerance with 8ppm/°C temperature coefficient, reducing output voltage drift by 20% compared to the MAX6164BESA. Supply current decreases to 18µA, and operating temperature extends to 125°C. Noise performance improves from 50µVp-p to 12µVp-p in the 0.1Hz to 10Hz band. These parts are suitable for precision analog applications where enhanced accuracy and thermal stability provide circuit benefits.

ADR292FRZ and ADR292FRZ-REEL7 provide ±0.1% tolerance with 15ppm/°C temperature coefficient, positioning them between the MAX6164BESA and ADR292ERZ in performance hierarchy. These parts maintain the same 5 mA output current and 8-SOIC package while offering reduced supply current and extended temperature range.

ADR292GRZ and ADR292GRZ-REEL7 operate at ±0.15% tolerance with 25ppm/°C temperature coefficient. These parts are functionally compatible where circuit design tolerates relaxed accuracy specifications, offering the lowest cost alternative within the active product portfolio.

Compliance and Availability: All substitute parts carry ROHS3 compliance and active product status, ensuring regulatory alignment and long-term supply continuity. Packaging format selection (tube, tape & reel, cut tape) depends on manufacturing process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can ADR292 series parts directly replace MAX6164BESA in existing designs? A: Yes. All ADR292 variants maintain the 4.096V fixed output, 5 mA output current, and 8-SOIC package form factor. Pin-for-pin compatibility is preserved. Performance improvements (lower tolerance, reduced noise, extended temperature range) do not introduce incompatibility. Circuit validation is not required for functional substitution.

Q: What is the difference between tube and tape & reel packaging? A: Tube packaging (MAX6164BESA+, ADR292ERZ, ADR292FRZ, ADR292GRZ) is suitable for manual assembly and low-volume production. Tape & reel packaging (ADR292ERZ-REEL, ADR292FRZ-REEL7, ADR292GRZ-REEL7) is optimized for automated pick-and-place assembly and high-volume manufacturing. Cut tape & Digi-Reel® format (ADR292GRZ-REEL7) provides flexibility for both manual and automated processes. Selection depends on production methodology and volume requirements.

Q: Why does MAX6164BESA+ exist if ADR292 series offers better performance? A: MAX6164BESA+ maintains identical electrical specifications to the obsolete MAX6164BESA, enabling direct substitution without design modification. This part serves applications where performance parameters are fixed by existing circuit design. ADR292 series parts are recommended for new designs where performance improvements can be leveraged.

Q: What is the impact of tolerance differences on circuit accuracy? A: Tolerance specification defines the maximum deviation of output voltage from the nominal 4.096V value. MAX6164BESA operates at ±0.12% (±4.915mV), ADR292ERZ at ±0.07% (±2.867mV), ADR292FRZ at ±0.1% (±4.096mV), and ADR292GRZ at ±0.15% (±6.144mV). Tighter tolerance improves reference accuracy in precision measurement and data acquisition circuits. Circuit design specifications determine acceptable tolerance range.

Q: Is RoHS compliance mandatory for substitution? A: RoHS compliance is determined by application requirements and regulatory jurisdiction. MAX6164BESA is RoHS non-compliant; all substitute parts carry ROHS3 compliance. Applications subject to RoHS directives (EU, China, Japan) require compliant components. Substitution to ROHS3-compliant parts (MAX6164BESA+, ADR292 series) satisfies regulatory requirements.

Q: What is the significance of temperature coefficient differences? A: Temperature coefficient quantifies output voltage drift across the operating temperature range. MAX6164BESA exhibits 10ppm/°C drift; ADR292ERZ exhibits 8ppm/°C. Over a 100°C temperature span, MAX6164BESA output drifts approximately 1024µV, while ADR292ERZ drifts 819µV. Lower temperature coefficient improves reference stability in applications experiencing wide thermal variation.

Q: Can ADR292GRZ substitute for MAX6164BESA in precision applications? A: ADR292GRZ operates at ±0.15% tolerance, which is looser than MAX6164BESA (±0.12%). Substitution is valid only where circuit design specifications permit ±0.15% accuracy. Precision analog applications (data acquisition, instrumentation) typically require tolerance equal to or tighter than the original specification. ADR292ERZ or ADR292FRZ are appropriate alternatives for precision applications.

Q: What inventory considerations apply to substitute selection? A: MAX6164BESA+ (2258 pcs), ADR292ERZ (2638 pcs), ADR292ERZ-REEL (4900 pcs), ADR292FRZ (2059 pcs), ADR292FRZ-REEL7 (3758 pcs), ADR292GRZ (1124 pcs), and ADR292GRZ-REEL7 (80433 pcs) are available in stock. ADR292GRZ-REEL7 offers the highest inventory level, supporting high-volume production requirements. Packaging format and performance specifications should drive selection; inventory availability is a secondary consideration.
