Product details
Overview
MAX4526EUA+T from Maxim Integrated is a high-speed phase-reversal analog switch IC configured as a bridge of two normally open and two normally closed CMOS switches, optimized for chopper-stabilized amplifiers. It operates from ±4.5V to ±18V dual supplies (or +4.5V to +36V single supply), delivers 175Ω max on-resistance with 8Ω matching, handles rail-to-rail analog signals from V− to V+, and guarantees break-before-make switching. Its 10pC max charge injection and <100ns transition time support precision DC/low-frequency signal inversion in metrology-grade instrumentation.
For engineers reviewing the MAX4526EUA+T datasheet, MAX4526EUA+T pinout, MAX4526EUA+T application, or MAX4526EUA+T equivalent, key selection criteria include guaranteed break-before-make timing, matched on-resistance flatness across temperature, low leakage (<0.5nA at +25°C), TTL/CMOS-compatible logic thresholds, and µMAX-8 package compatibility with high-density analog routing constraints.
Technical Context
The MAX4526EUA+T implements a fully integrated bridge topology where A/B serve as differential inputs and X/Y as differential outputs, with IN controlling signal polarity reversal via complementary switch activation. Its internal logic-level translator drives N- and P-channel MOSFETs out-of-phase using V+ and V−, enabling true rail-to-rail conduction without ground reference.
All analog terminals (A, B, X, Y) feature ESD diodes to both V+ and V−-not GND-enabling bipolar operation down to V− while ensuring leakage current flows only to supply rails. The device is factory-characterized at ±15V, with on-resistance flatness (≤12Ω), charge-injection matching (≤2pC), and isolation (>65dB at 1MHz) all specified over −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±18V dual or +4.5V to +36V single - supports industrial bipolar rails and wide-input power architectures |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation and gain error in precision gain-setting paths |
| RON Matching (∆RON) | 8Ω max between A-X/A-Y/B-X/B-Y - critical for balanced modulator carrier suppression and chopper amplifier offset cancellation |
| Charge Injection | 10pC max - limits voltage glitch on high-impedance nodes (e.g., integrator capacitors in auto-zeroing circuits) |
| Transition Time | <100ns at ±15V - enables reliable operation up to 100kHz carrier frequencies in balanced modulators |
| Leakage Current | 0.5nA max at +25°C, 10nA at +85°C - preserves accuracy in picoampere-level sensor front-ends and electrometer designs |
| ESD Protection | >2kV per Method 3015.7 - safeguards against handling damage during PCB assembly and field service |
Pinout & Package
MAX4526EUA+T is housed in an 8-pin µMAX package (pin pitch 0.65mm, body size 3.05mm × 3.05mm × 0.91mm), optimized for space-constrained analog signal chains. The package features exposed pad thermal enhancement and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Analog input terminal A | Connected to Y when IN = LOW; to X when IN = HIGH - forms one leg of differential input pair |
| 2 (B) | Analog input terminal B | Connected to X when IN = LOW; to Y when IN = HIGH - complementary leg for phase-reversal symmetry |
| 3 (GND) | Digital ground reference | Reference for logic circuitry only; analog path is floating between V+ and V− - requires separation from analog ground planes |
| 4 (IN) | Logic control input | TTL/CMOS-compatible (0.8V–2.4V thresholds); drives internal translator to toggle bridge state - no external pull-up required |
| 5 (V−) | Negative analog supply | Sets lower analog rail limit; internally connected to ESD diodes - must be tied to GND for single-supply operation |
| 6 (Y) | Analog output terminal Y | Output node for inverted or non-inverted signal depending on IN state - bidirectional, rail-to-rail capable |
| 7 (X) | Analog output terminal X | Complementary output node to Y - used with Y to deliver balanced differential output |
| 8 (V+) | Positive analog/digital supply | Powers analog switches and logic; internally tied to substrate - bypass with 0.1µF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing fully from V− to V+ without clipping - eliminates level-shifting in ±15V systems |
| Guaranteed break-before-make | 1ns–5ns delay prevents momentary short-circuit between X and Y during switching - essential for stable chopper feedback loops |
| 10pC max charge injection | Minimizes transient voltage error on capacitive loads (e.g., 10nF integrators), reducing settling time in auto-zero cycles |
| 2pC max charge-injection match | Ensures common-mode rejection in differential paths - directly improves carrier suppression in modulator applications |
| 175Ω on-resistance flatness ≤12Ω | Maintains consistent gain and phase response across full analog input range (±15V) - critical for THD-sensitive audio routing |
Applications
| Chopper-Stabilized Amplifiers | Balanced Modulators/Demodulators |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-reversal analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4527EUA+T | Identical analog switch architecture but slower transition time (250ns vs. <100ns) and lower supply current (1µA vs. 1.5mA typical at +25°C) | Optimized for ultra-low-power battery-operated systems rather than high-speed chopper or modulator use | Select MAX4527EUA+T only when transition speed is non-critical and supply current must be minimized below 2µA |
| ADG1419BRMZ | Single-pole double-throw (SPDT) topology instead of bridge; 1.5Ω on-resistance but no inherent phase-reversal capability - requires external wiring | Requires discrete resistor networks and layout symmetry to emulate phase reversal - increases board area and mismatch risk | Choose ADG1419BRMZ only if system already uses ADI's precision switch portfolio and can accommodate external balancing components |
Compared with MAX4527EUA+T, the MAX4526EUA+T trades higher quiescent current for 2.5× faster switching and tighter RON matching - making it the sole choice for chopper amplifiers above 50kHz. Against ADG1419BRMZ, it delivers native bridge functionality with guaranteed break-before-make, eliminating layout-dependent performance variation.

FAQ
What is the operating temperature range for MAX4526EUA+T?
The MAX4526EUA+T is rated for −40°C to +85°C operation, validated across this full industrial temperature range for parameters including on-resistance matching, leakage current, and transition time. This rating is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, with all electrical characteristics guaranteed over this span.
Can MAX4526EUA+T operate from a single supply?
Yes, MAX4526EUA+T supports single-supply operation from +4.5V to +36V by connecting V− to GND. The analog signal range remains rail-to-rail (0V to V+), and all key specs-including 175Ω max on-resistance and <100ns transition time-are maintained. However, bipolar supply operation (±4.5V to ±18V) is required to achieve optimal AC symmetry and carrier suppression in modulator applications.
Is MAX4526EUA+T pin-compatible with MAX4527EUA+T?
Yes, MAX4526EUA+T and MAX4527EUA+T share identical pinout, package (8-pin µMAX), and footprint. They differ only in internal logic driver speed and supply current - the MAX4526EUA+T uses a faster translator for <100ns transitions, while the MAX4527EUA+T reduces current to 1µA. No PCB changes are needed when substituting between these variants.
What is the maximum analog signal frequency supported by MAX4526EUA+T?
MAX4526EUA+T is characterized for DC and low-frequency phase reversal up to 100kHz, as verified in balanced modulator applications (Figure 2). Its −3dB bandwidth exceeds 10MHz, but carrier suppression degrades above 100kHz due to internal capacitance/resistance imbalances. For optimal performance, use within 100kHz with precise 50% duty-cycle square-wave control on the IN pin.
How does the break-before-make timing affect chopper amplifier design?
The guaranteed 1ns–5ns break-before-make interval in MAX4526EUA+T prevents momentary short-circuit between X and Y outputs during polarity reversal - a critical requirement in chopper amplifier feedback loops. This eliminates output glitches that would otherwise corrupt integrator reset cycles and cause residual offset or instability in auto-zeroing topologies.
