Substitute Part Grouping Explanation

Substitution for the MAX4523CEE+ is determined by the following core parameters: SPST NO/NC switch circuit topology, 4-circuit configuration, 1:1 multiplexer/demultiplexer ratio, surface mount assembly, and compliance certifications (ROHS3, REACH Unaffected, EAR99). All substitute parts maintain these fundamental characteristics.

Substitute parts are grouped by on-state resistance performance tier:

Low Resistance Tier (1.1Ohm - 1.8Ohm): ADG1413YRUZ, ADG1413YRUZ-REEL7, ADG1613BRUZ, ADG1613BRUZ-REEL, ADG1613BRUZ-REEL7 — optimized for applications requiring minimal signal attenuation and power dissipation.

Mid Resistance Tier (5.1Ohm - 200Ohm): ADG4613BRUZ, ADG1213YRUZ, ADG1213YRUZ-REEL7, ADG1313YRUZ, ADG1313YRUZ-REEL7 — suitable for general-purpose switching applications with moderate impedance requirements.

All substitute parts are active products with extended operating temperature ranges (-40°C to 125°C or -40°C to 105°C) compared to the obsolete MAX4523CEE+ (0°C to 70°C), and are packaged in 16-TSSOP format with improved electrical characteristics.

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original MAX4523CEE+.

For Low-Impedance Applications: ADG1613BRUZ and ADG1613BRUZ-REEL provide the lowest on-state resistance (1.1Ohm) with superior channel-to-channel matching (30mOhm) and extended temperature operation (-40°C to 125°C). These parts are suitable for precision signal routing and low-loss switching paths.

For General-Purpose Switching: ADG1413YRUZ and ADG1413YRUZ-REEL7 offer moderate on-state resistance (1.8Ohm) with excellent crosstalk performance (-100dB @ 1MHz) and active product status across full temperature range (-40°C to 125°C).

Frequently Asked Questions (FAQ)

Q: Can ADG1213YRUZ directly replace MAX4523CEE+ without PCB modifications?

A: Electrical substitution is possible; however, package geometry differs. MAX4523CEE+ uses 16-SSOP (3.90mm width), while ADG1213YRUZ uses 16-TSSOP (4.40mm width). PCB footprint adjustment is required. Pin-to-pin functionality is equivalent for SPST NO/NC switching topology.

Q: What is the primary difference between ADG1613BRUZ and ADG1413YRUZ?

A: ADG1613BRUZ features lower on-state resistance (1.1Ohm vs. 1.8Ohm), superior channel-to-channel matching (30mOhm vs. 100mOhm), and lower crosstalk (-110dB vs. -100dB @ 1MHz). ADG1413YRUZ offers faster switch times (150ns/120ns vs. 156ns/87ns) and lower charge injection (-20pC vs. 170pC). Selection depends on whether impedance matching or switching speed is prioritized.

Q: Are packaging variants (Tube, Cut Tape & Digi-Reel, Tape & Reel) electrically identical?

A: Yes. ADG1213YRUZ, ADG1213YRUZ-REEL7, ADG1313YRUZ, ADG1313YRUZ-REEL7, ADG1413YRUZ, ADG1413YRUZ-REEL7, ADG1613BRUZ, ADG1613BRUZ-REEL, and ADG1613BRUZ-REEL7 are electrically identical. Packaging differences affect only handling, storage, and supply chain logistics, not electrical performance.

Q: Which substitute part best matches the MAX4523CEE+ operating temperature range?

A: The MAX4523CEE+ operates 0°C to 70°C. All substitute parts extend this range to -40°C to 125°C (ADG1213YRUZ, ADG1413YRUZ, ADG1613BRUZ) or -40°C to 105°C (ADG1313YRUZ, ADG4613BRUZ), providing broader environmental capability for extended applications.

Q: What supply voltage range should be selected for a ±5V dual supply system?

A: ADG1613BRUZ supports ±3.3V to ±8V dual supply, accommodating ±5V operation. ADG4613BRUZ supports ±3V to ±5.5V dual supply, also suitable for ±5V. ADG1213YRUZ and ADG1413YRUZ require ±4.5V to ±16.5V dual supply, exceeding ±5V requirements. ADG1313YRUZ requires ±15V dual supply and is not suitable for ±5V systems.

Q: Is the MAX4523CEE+ still available for new designs?

A: No. MAX4523CEE+ is classified as obsolete. Active substitute parts from Analog Devices Inc. (ADG series) are recommended for all new designs and production requirements.
