Substitute Part Grouping Explanation

Substitution of the MAX501BENG with the AD7845JNZ is based on strict equivalence of the following critical parameters:

• Resolution & Architecture: Both devices are 12-bit DACs utilizing R-2R ladder architecture
• Functional Configuration: Single DAC channel with buffered voltage output and external reference capability
• Data Interface: Parallel interface for both components
• Electrical Performance: Identical settling time (5µs) and INL/DNL specifications (±1 LSB Max)
• Package Compatibility: Both use 24-DIP (0.300", 7.62mm) through-hole packaging
• Differential Output: Neither device provides differential output capability

The AD7845JNZ maintains full functional and electrical equivalence to the MAX501BENG while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The AD7845JNZ is the manufacturer-recommended substitute for the MAX501BENG and provides full functional equivalence for applications within its specified operating parameters. Key considerations for component selection:

Operating Temperature Range: The AD7845JNZ operates over 0°C to 70°C, compared to the MAX501BENG range of -40°C to 85°C. Applications requiring extended temperature operation below 0°C or above 70°C must verify compatibility with the narrower specification.

Analog Supply Voltage Range: The AD7845JNZ accepts analog supply voltages from ±14.25V to ±15.75V, whereas the MAX501BENG accepts ±11.4V to ±15.75V. Designs operating with analog supply voltages below ±14.25V require verification of compatibility.

Compliance & Product Status: The AD7845JNZ holds active product status with ROHS3 compliance and REACH unaffected certification, providing superior long-term availability and regulatory alignment compared to the obsolete MAX501BENG.

Electrical Performance: Both devices maintain identical settling time (5µs), resolution (12-bit), and linearity specifications (±1 LSB INL/DNL), ensuring equivalent performance in data acquisition applications.

Frequently Asked Questions (FAQ)

Q: Can the AD7845JNZ directly replace the MAX501BENG in existing designs?

A: The AD7845JNZ provides direct functional replacement for the MAX501BENG in applications where operating temperature remains within 0°C to 70°C and analog supply voltage remains within ±14.25V to ±15.75V. Designs operating outside these ranges require engineering evaluation.

Q: Are there package compatibility concerns between these devices?

A: Both the MAX501BENG and AD7845JNZ use identical 24-DIP (0.300", 7.62mm) through-hole packaging. No PCB layout modifications are required for physical substitution.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in resolution (12-bit), DAC count (1), output type (voltage-buffered), data interface (parallel), architecture (R-2R), settling time (5µs), and linearity specifications (±1 LSB INL/DNL). All these parameters are identical between the two devices.

Q: Does the AD7845JNZ require different reference circuitry than the MAX501BENG?

A: Both devices utilize external reference configuration. Reference circuitry design remains unchanged between the two components.

Q: What compliance advantages does the AD7845JNZ offer?

A: The AD7845JNZ is ROHS3 compliant and maintains active product status, providing improved regulatory alignment and long-term supply availability compared to the obsolete, RoHS non-compliant MAX501BENG.

Q: Are there any settling time or performance differences between these devices?

A: No. Both devices specify identical settling time (5µs) and linearity performance (±1 LSB INL/DNL), ensuring equivalent data acquisition performance.
