Product details
Overview
MAX4525LEUB+T from Maxim Integrated is a low-voltage, single-supply CMOS double-pole/double-throw (DPDT) analog switch configured for bidirectional signal routing in precision analog systems. It operates from +2V to +12V, delivers 100Ω on-resistance at +12V, guarantees ≤2nA off-leakage at +25°C, and supports rail-to-rail analog signals - enabling use in DSL modems and audio/video routing where channel matching and low charge injection are critical.
For engineers reviewing the MAX4525LEUB+T datasheet, MAX4525LEUB+T pinout, MAX4525LEUB+T application, or MAX4525LEUB+T equivalent, key selection criteria include its DPDT topology, 10-pin µMAX package, guaranteed 10Ω on-resistance match, 96dB channel-to-channel crosstalk, and TTL/CMOS-compatible logic thresholds (VIH = 2.0V, VIL = 0.8V) with +12V supply.
Technical Context
The MAX4525LEUB+T implements a true DPDT switch architecture with two independent COM/NO/NC paths (COMA–NOA/NCA and COMB–NOB/NCB), controlled by a single ADD address input and shared INH inhibit. Its internal logic-level translators isolate digital control from analog signal paths, eliminating ground reference requirements for analog signals.
All switches feature matched on-resistance (≤10Ω max mismatch at +12V), low 0.8pC charge injection, and flat on-resistance over full signal range (≤12Ω flatness). Off-isolation exceeds 92dB at 1MHz, and -3dB bandwidth reaches 200MHz - confirming suitability for high-fidelity audio and broadband communications switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V - enables direct interface with 3.3V and 5V logic while maintaining rail-to-rail analog swing |
| On-Resistance (RON) | 100Ω max at +12V - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths |
| On-Resistance Match (∆RON) | 10Ω max at +12V - guarantees consistent gain and phase response across both poles in differential or stereo applications |
| Off-Leakage Current | 2nA max at +25°C - preserves accuracy in high-impedance circuits like medical front-ends or data-acquisition sample-hold stages |
| Charge Injection | 0.8pC typical - minimizes voltage glitch during switching, critical for low-distortion multiplexing in ADC/DAC interfaces |
| Crosstalk | 96dB at 1MHz - prevents signal coupling between channels in dual-path communication or stereo audio routing |
| Bandwidth (-3dB) | 200MHz - supports video, broadband RF IF, and high-speed serial signal routing without roll-off |
Pinout & Package
The MAX4525LEUB+T is housed in a 10-pin µMAX package (3mm × 3mm, 0.8mm height), RoHS-compliant, with exposed pad not present (unlike TDFN variant). Pin 10 is V+, Pin 5 is GND, and all analog terminals (COMA, NOA, NCA, COMB, NOB, NCB) support bidirectional rail-to-rail operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NOA | Analog Switch A Normally Open Input | Connects to COMA when ADD = 1; open-circuit otherwise - forms one pole of DPDT path |
| 2 COMA | Analog Switch A Common Terminal | Primary signal I/O node for Pole A; accepts rail-to-rail voltages from GND to V+ |
| 3 NCA | Analog Switch A Normally Closed Input | Connects to COMA when ADD = 0; open-circuit otherwise - provides break-before-make switching |
| 4 INH | Inhibit Control Input | Drives all switches OFF when high (≥2.0V); must be tied to GND or logic low for normal operation |
| 5 GND | Digital Ground Reference | Reference for logic inputs only; no analog signal ground connection required |
| 6 ADD | Address Select Input | Single-bit control: ADD = 0 → COMA–NCA / COMB–NCB; ADD = 1 → COMA–NOA / COMB–NOB |
| 7 COMB | Analog Switch B Common Terminal | Second pole common node; electrically isolated from COMA but shares same control logic |
| 8 NOB | Analog Switch B Normally Open Input | Connects to COMB when ADD = 1 - completes second pole of DPDT configuration |
| 9 NCB | Analog Switch B Normally Closed Input | Connects to COMB when ADD = 0 - enables complementary switching for polarity reversal or signal inversion |
| 10 V+ | Positive Supply | Powers analog switches and internal logic; requires 0.1µF bypass capacitor to GND for stability |
Key Features
| Feature | Design Value |
|---|---|
| DPDT Switch Topology | Two fully independent, TTL/CMOS-controlled poles enable signal polarity reversal, differential path selection, or redundant routing without external components |
| Guaranteed On-Resistance Match | ≤10Ω max difference between COMA–NOA and COMB–NOB at +12V - ensures balanced performance in stereo or differential applications |
| Break-Before-Make Timing | 20ns typical - prevents momentary shorting during state transitions, protecting sensitive downstream circuitry |
| Low Off-Capacitance | 6pF COM off-capacitance - minimizes loading on high-impedance sources and preserves signal integrity in RF and audio paths |
| TTL/CMOS Logic Compatibility | VIH = 2.0V / VIL = 0.8V thresholds with +12V supply - eliminates need for level shifters when interfacing with standard microcontrollers or FPGAs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG732BRUZ | 32-channel SPST, 4Ω RON at +3.3V; no DPDT topology; requires external logic for pole pairing | Designed for high-channel-count, low-voltage (1.8–5.5V) data acquisition - lacks integrated DPDT control | Select when scaling to >2 poles or operating below +2.5V; not drop-in for MAX4525LEUB+T's dual-pole function |
| TS5A3157DCKR | SPDT, 0.75Ω RON at +1.8V; single-pole only; 1.8–5.5V supply; 12ns tON | Optimized for portable battery-powered audio switching - no NC path or inhibit function | Choose for ultra-low RON in single-pole, low-voltage designs; cannot replicate MAX4525LEUB+T's break-before-make DPDT behavior |
Compared with ADG732BRUZ and TS5A3157DCKR, the MAX4525LEUB+T uniquely integrates dual-pole, double-throw functionality with inhibit control and rail-to-rail operation up to +12V - making it irreplaceable in DSL line interface and professional audio matrix applications requiring coordinated polarity reversal.

FAQ
What is the maximum supply voltage rating for the MAX4525LEUB+T?
The MAX4525LEUB+T has an absolute maximum supply voltage of +13V, with recommended operating range 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.
Does the MAX4525LEUB+T require a ground connection for analog signals?
No - the MAX4525LEUB+T does not require analog signal ground reference. Its analog terminals (COMA, NOA, NCA, COMB, NOB, NCB) operate rail-to-rail between GND and V+, with no internal connection to GND. Only digital control inputs (ADD, INH) and V+/GND pins reference the ground plane.
How does the INH pin function on the MAX4525LEUB+T?
The INH pin on the MAX4525LEUB+T is an active-high inhibit input: driving INH ≥2.0V opens all switches (COMA/NCA/NOA and COMB/NCB/NOB), regardless of ADD state. For normal DPDT operation, INH must be tied to GND or held at ≤0.8V. This provides system-level fault protection and power-down capability.
What is the guaranteed on-resistance match between poles in the MAX4525LEUB+T?
The MAX4525LEUB+T guarantees ≤10Ω maximum on-resistance mismatch (∆RON) between COMA–NOA and COMB–NOB paths at +12V and +25°C. Over full temperature range (−40°C to +85°C), ∆RON remains ≤15Ω - ensuring matched insertion loss and phase response in stereo, differential, or dual-path applications.
Can the MAX4525LEUB+T be used with a 3.3V supply?
Yes - the MAX4525LEUB+T operates from +2V to +12V. At +3.3V, on-resistance increases to ~300Ω (typical), off-leakage remains ≤10nA, and logic thresholds (VIH = 2.0V, VIL = 0.8V) remain compatible with 3.3V CMOS outputs. Performance trade-offs include reduced bandwidth and higher RON-induced THD.
