Product details
Overview
MAX4527EUA from Maxim Integrated is a low-power, ±4.5V to ±18V dual-supply (or +4.5V to +36V single-supply) phase-reversal analog switch IC in an 8-pin µMAX package. It features rail-to-rail signal handling, 175Ω max on-resistance, 10pC max charge injection, guaranteed break-before-make switching, and 1µA supply current at +25°C - optimized for chopper-stabilized amplifiers and precision self-calibrating circuits.
For engineers reviewing the MAX4527EUA datasheet, MAX4527EUA pinout, MAX4527EUA application, or MAX4527EUA equivalent, key selection criteria include its low-leakage (0.5nA @ +25°C), matched on-resistance (≤8Ω), TTL/CMOS-compatible logic inputs, ESD robustness (>2kV), and temperature range (-40°C to +85°C) for industrial-grade analog signal routing.
Technical Context
The MAX4527EUA implements a bridge-configured phase-reversal topology with two normally open and two normally closed CMOS switches. Its internal logic-level translator drives N- and P-channel MOSFETs out-of-phase using V+ and V− to enable rail-to-rail analog conduction without ground reference.
It operates with bipolar supplies (±4.5V to ±18V) or single supply (+4.5V to +36V), where V− is tied to GND. Analog signal paths (A/B/X/Y) are fully bidirectional, and AC symmetry is optimized when A/B serve as inputs and X/Y as outputs - critical for balanced modulator/demodulator performance up to 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±18V dual or +4.5V to +36V single - supports wide industrial voltage rails and simplifies power design across bipolar and unipolar systems. |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation and gain error in precision DC/low-frequency paths. |
| On-Resistance Match (∆RON) | 8Ω max - guarantees tight channel-to-channel gain matching essential for chopper amplifier offset cancellation. |
| Charge Injection | 10pC max - limits voltage glitch on high-impedance nodes (e.g., integrator capacitors), preserving accuracy in auto-zeroing circuits. |
| Leakage Current | 0.5nA max at +25°C, 10nA at +85°C - enables stable DC biasing in nanoamp-level sensor interfaces and high-Z sample-hold stages. |
| Transition Time | <100ns at ±15V - sufficient for 100kHz carrier modulation while maintaining clean edge integrity in timing-critical phase reversal. |
| ESD Protection | >2kV per Method 3015.7 - enhances reliability in bench-test and production environments without external protection. |
Pinout & Package
MAX4527EUA is housed in an 8-pin µMAX package (2.1mm × 1.6mm, 0.5mm pitch), compatible with space-constrained PCB layouts and offering thermal dissipation of 330mW at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Analog input/output terminal A | Connected to Y when IN = LOW; to X when IN = HIGH - forms one leg of the phase-reversal bridge. |
| 2 (B) | Analog input/output terminal B | Connected to X when IN = LOW; to Y when IN = HIGH - complementary leg enabling polarity inversion. |
| 3 (GND) | Digital ground reference | Reference for logic inputs only; analog signals are fully floating between V+ and V− - eliminates ground-loop coupling. |
| 4 (IN) | Logic control input | TTL/CMOS-compatible (0.8V–2.4V thresholds); controls switch state with guaranteed break-before-make timing (1–5ns). |
| 5 (V−) | Negative analog supply | Sets lower analog rail limit; tied to GND for single-supply operation - defines signal swing floor and P-MOSFET gate drive. |
| 6 (Y) | Analog output/input terminal Y | Output when IN = LOW (A→Y, B→X); output when IN = HIGH (A→X, B→Y) - bidirectional, rail-to-rail capable. |
| 7 (X) | Analog output/input terminal X | Complementary output to Y; completes bridge routing - maintains signal symmetry when paired with Y. |
| 8 (V+) | Positive analog/digital supply | Powers analog switches and internal logic; internally connected to substrate - sets upper analog rail and N-MOSFET gate drive. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V− to V+ with no ground dependency - enables true differential operation in isolated or floating systems. |
| Guaranteed break-before-make | 1–5ns minimum delay prevents momentary shorting during state transition - critical for avoiding signal transients in feedback loops. |
| 10pC max charge injection | Minimizes voltage step on high-impedance capacitive nodes (e.g., integrators), reducing settling error in chopper-stabilized amplifiers. |
| 1µA supply current (MAX4527) | Enables ultra-low-power operation in battery-backed instrumentation and portable calibration modules without sacrificing analog performance. |
| Matched on-resistance (≤8Ω) | Ensures identical gain scaling across both signal paths - essential for common-mode rejection in balanced modulators and demodulators. |
| TTL/CMOS-compatible inputs | Operates reliably with standard microcontroller GPIOs or logic families across full supply range - eliminates level-shifting circuitry. |
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 |
|---|---|---|---|
| MAX4526EUA | Higher supply current (1.5mA vs. 1µA), faster transition time (<70ns vs. <100ns), same pinout and RON specs | Better suited for higher-frequency chopper or modulator use (>100kHz), less suitable for ultra-low-power battery operation | Select MAX4526EUA when speed outweighs power budget; otherwise MAX4527EUA offers optimal trade-off for precision DC/low-freq systems. |
| ADG1419BRMZ | Single 8-pin SPDT configuration (not bridge), 1.5Ω RON, ±15V rating, but no inherent phase-reversal function or break-before-make guarantee | Requires external wiring to emulate phase reversal, increasing layout complexity and degrading AC balance vs. integrated bridge | Choose ADG1419BRMZ only if discrete SPDT switching suffices; MAX4527EUA provides native, optimized phase reversal in one device. |
Compared with MAX4526EUA, the MAX4527EUA trades speed for 1500× lower quiescent current - making it superior for battery-powered instrumentation. Against ADG1419BRMZ, MAX4527EUA delivers integrated bridge topology with guaranteed break-before-make and matched RON, eliminating external components and improving system-level symmetry.

FAQ
What is the operating temperature range for the MAX4527EUA?
The MAX4527EUA is rated for -40°C to +85°C operation, validated across all electrical specifications including on-resistance, leakage current, and transition time. This extended industrial temperature range ensures reliable performance in harsh environments such as factory automation controllers and outdoor instrumentation - unlike the commercial-grade MAX4527CUA (0°C to +70°C).
Does the MAX4527EUA support single-supply operation?
Yes, the MAX4527EUA supports single-supply operation from +4.5V to +36V by connecting V− to GND. All analog signal paths remain rail-to-rail (0V to V+), and logic inputs retain TTL/CMOS compatibility. However, bipolar supply operation (±4.5V to ±18V) is recommended for optimal AC symmetry in modulator applications.
How does the MAX4527EUA achieve phase reversal?
The MAX4527EUA uses an internal bridge configuration of four CMOS switches (two NO, two NC) controlled by the IN pin. When IN is LOW, A connects to Y and B connects to X; when IN is HIGH, A connects to X and B connects to Y - physically swapping the signal paths to invert polarity. No external components are needed to realize true analog phase reversal.
What is the significance of guaranteed break-before-make in the MAX4527EUA?
The MAX4527EUA guarantees a 1–5ns break-before-make interval during switching, preventing momentary short-circuit between X and Y outputs. This eliminates transient glitches in sensitive feedback paths - especially critical in chopper amplifier integrator stages where even nanosecond shorts cause measurable offset errors.
Can the MAX4527EUA be used with asymmetric dual supplies?
Yes - the MAX4527EUA accepts asymmetric dual supplies as long as the absolute maximum ratings are respected: V+ ≤ +44V, V− ≥ -25V, and |V+ − V−| ≤ 44V. For example, +12V and -5V is valid. However, analog signal range becomes V− to V+, and on-resistance and leakage are characterized at ±15V; performance at asymmetric rails should be verified per application.
