Product details
Overview
MAX4525LEUB+ from Maxim Integrated is a low-voltage, single-supply CMOS double-pole/double-throw (DPDT) analog switch in a 10-pin µMAX package, operating from +2V to +12V supply, delivering 100Ω on-resistance at +12V, 2nA max off-leakage at +25°C, and rail-to-rail signal handling - used for precision signal routing in DSL modems and communications circuits.
For engineers reviewing the MAX4525LEUB+ datasheet, MAX4525LEUB+ pinout, MAX4525LEUB+ application, or MAX4525LEUB+ equivalent, key selection criteria include guaranteed 10Ω on-resistance match, break-before-make timing (20ns), THD of 0.02% at audio bandwidth, and TTL/CMOS logic compatibility with 0.8V–2.0V thresholds under +12V operation.
Technical Context
The MAX4525LEUB+ implements a true DPDT topology with two independent SPDT sections (COMA/NOA/NCA and COMB/NOB/NCB), each controlled by a shared ADD address input and global INH inhibit. Its CMOS architecture enables rail-to-rail analog conduction without level-shifting circuitry.
All digital inputs are referenced to V+ and GND only - no internal ground reference exists for analog paths; leakage current arises solely from reverse-biased ESD diodes between signal pins and V+/GND, resulting in temperature-dependent but highly predictable off-state behavior (±25nA max over –40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - supports direct interface with 3.3V and 5V logic while maintaining full rail-to-rail analog swing |
| On-Resistance (RON) | 100Ω max at +12V - ensures minimal insertion loss and voltage drop in precision signal paths |
| On-Resistance Match (∆RON) | 15Ω max over temperature - critical for matched gain/phase in differential or dual-channel routing |
| Off-Leakage Current | ±25nA max at –40°C to +85°C - preserves signal integrity in high-impedance sensor or audio front-end nodes |
| Bandwidth | 200MHz –3dB - supports video, broadband data, and high-speed serial signal switching |
| Charge Injection | 0.8pC typical - minimizes transient glitches during switching in sample-and-hold or multiplexed ADC systems |
| Logic Thresholds | VIH = 1.5V–2.0V, VIL = 0.18V–1.5V - ensures robust TTL/CMOS compatibility across supply voltages |
Pinout & Package
Package: 10-pin µMAX (3mm × 3mm, exposed pad not present in µMAX variant - only in TDFN-EP). Pin 10 is V+, Pin 5 is GND, Pin 4 is INH (active-high inhibit), Pins 6/7 are ADD (address control), Pins 1/2/3/8/9 are analog terminals configured as COMA, NOA, NCA, COMB, NOB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NOA | Analog switch A normally open terminal - connects to COMA when enabled; isolated otherwise |
| 2 | COMA | Common terminal for switch A - bidirectional path between NOA and NCA |
| 3 | NCA | Analog switch A normally closed terminal - connects to COMA when INH = low and ADD = 0 |
| 4 | INH | Global inhibit input - high (≥2.0V) forces all switches open regardless of ADD state |
| 5 | GND | Digital ground reference for logic circuitry only - no analog signal reference |
| 6 | ADD | Address select input - controls pole A/B connection state (0 = COM–NCA/COMB–NCB, 1 = COM–NOA/COMB–NOB) |
| 7 | V+ | Positive supply for analog switches and logic - must be bypassed with 0.1µF to GND |
| 8 | COMB | Common terminal for switch B - bidirectional path between NOB and NCB |
| 9 | NOB | Analog switch B normally open terminal - connects to COMB when enabled |
| 10 | NCB | Analog switch B normally closed terminal - connects to COMB when INH = low and ADD = 0 |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | 20ns guaranteed - prevents momentary shorting between NC and NO paths during switching |
| Rail-to-rail signal handling | Full V+ to GND analog range supported - eliminates need for external level shifters or bias networks |
| Low THD | 0.02% at 20Hz–20kHz - preserves fidelity in audio and instrumentation signal chains |
| Off-isolation | 92dB at 1MHz - suppresses crosstalk between active and inactive channels in dense routing |
| Channel-to-channel crosstalk | 96dB at 1MHz (MAX4525L only) - enables simultaneous high-fidelity dual-path routing without interference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4525LETB+ | Same die, 10-pin TDFN-EP (3mm × 3mm) with exposed pad tied to V+ - lower thermal resistance (24.4mW/°C derating vs. 5.6mW/°C for µMAX) | Better power dissipation in high-density or thermally constrained PCB layouts; requires different land pattern | Select MAX4525LETB+ when board space allows TDFN and thermal management is critical; MAX4525LEUB+ preferred for legacy µMAX footprints. |
| ADG732BRUZ | 32-channel, single-pole/single-throw (SPST) CMOS switch; no DPDT topology; 4Ω on-resistance at +5V but only 5.5V max supply | Requires external logic to emulate DPDT behavior; unsuitable for rail-to-rail >5.5V signals or single-wire address control | Choose ADG732BRUZ only for high-channel-count, low-RON, low-voltage (<5.5V) systems where discrete control logic is acceptable. |
Compared with MAX4525LETB+, the MAX4525LEUB+ offers identical electrical performance in a legacy-compatible µMAX package but with higher thermal resistance; versus ADG732BRUZ, it provides native DPDT functionality, wider supply range (+2V to +12V), and single-pin address control - eliminating FPGA/GPIO overhead in space-constrained designs.

FAQ
What is the maximum supply voltage rating for MAX4525LEUB+?
The MAX4525LEUB+ has an absolute maximum supply voltage of +13V, with recommended continuous operation from +2V to +12.6V. Operation at +12V optimizes on-resistance to 100Ω and ensures full TTL/CMOS logic compatibility. Exceeding +13V risks permanent damage due to internal ESD diode breakdown, as specified in the Absolute Maximum Ratings table.
Does MAX4525LEUB+ support rail-to-rail analog signals?
Yes, the MAX4525LEUB+ supports rail-to-rail analog signals from GND to V+. This is achieved through its CMOS switch architecture with no internal level-shifting circuitry - allowing signals equal to the supply rails to pass without clipping or distortion, provided V+ remains within its rated range and analog pins do not exceed V+ or go below GND.
What is the function of the INH pin on MAX4525LEUB+?
The INH (inhibit) pin on MAX4525LEUB+ is an active-high control that forces all analog switches into the open (off) state regardless of the ADD input state. When INH ≥ 2.0V, both DPDT sections disconnect simultaneously - providing fail-safe signal isolation during system reset, fault conditions, or power sequencing. Pulling INH to GND enables normal address-controlled switching.
Can MAX4525LEUB+ operate from a 3.3V supply?
Yes, MAX4525LEUB+ operates from +2V to +12V, including 3.3V. At 3.3V, on-resistance increases (typical ~300Ω), and logic thresholds remain compatible (VIH = 1.5V–2.0V, VIL = 0.18V–1.5V), ensuring reliable control from standard 3.3V GPIOs. However, rail-to-rail analog swing is reduced to 0V–3.3V, and off-leakage rises slightly versus +12V operation.
Is the µMAX package of MAX4525LEUB+ RoHS compliant?
Yes, the MAX4525LEUB+ carries the "+" suffix, indicating RoHS-compliant packaging per Maxim Integrated's documentation. The 10-pin µMAX package (U10-2) uses lead-free terminations and meets JEDEC J-STD-609 Category 1 requirements. Full compliance documentation, including material declarations, is available via Analog Devices' product page for MAX4525LEUB+.
