Product details
Overview
MAX4527ESA from Maxim Integrated is a low-power phase-reversal analog switch IC configured as a bridge of two normally open and two normally closed CMOS switches. It operates from ±4.5V to ±18V dual supplies or +4.5V to +36V single supply, delivers 175Ω max on-resistance with 8Ω matching, supports rail-to-rail analog signals up to ±15V, and consumes only 1µA at +25°C - ideal for chopper-stabilized amplifiers requiring precision polarity inversion.
For engineers reviewing the MAX4527ESA datasheet, MAX4527ESA pinout, MAX4527ESA application, or MAX4527ESA equivalent, this page provides verified pin functions, real-world leakage and charge-injection performance, temperature-rated switching behavior, and validated alternatives for low-power phase-reversal signal routing in precision analog systems.
Technical Context
The MAX4527ESA implements a fully differential bridge topology where logic-controlled IN selects between two complementary signal paths: A→Y/B→X (IN = LOW) or A→X/B→Y (IN = HIGH), enabling true DC-coupled phase reversal. Its internal logic-level translator drives N- and P-channel MOSFET gates with out-of-phase V+ and V− signals, ensuring rail-to-rail conduction without ground reference.
All four analog terminals (A, B, X, Y) are bidirectional and electrically identical; AC symmetry is optimized when A/B serve as inputs and X/Y as outputs. Break-before-make timing is guaranteed at 1–5ns, and ESD protection exceeds 2kV per Method 3015.7 - critical for test equipment and data acquisition environments subject to handling stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±18V dual or +4.5V to +36V single - enables operation in industrial bipolar rails or battery-powered single-supply systems. |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation and gain error in precision instrumentation front-ends. |
| RON Matching (∆RON) | 8Ω max between A-X/A-Y/B-X/B-Y - preserves amplitude balance essential for carrier suppression in modulators. |
| Charge Injection | 10pC max - limits voltage glitch on high-impedance nodes (e.g., integrator capacitors in chopper amps). |
| Leakage Current | 0.5nA at +25°C, 10nA at +85°C - maintains accuracy in µV-level DC measurements over temperature. |
| Transition Time | 250ns max at ±15V - supports phase reversal up to ~100kHz carrier frequencies in balanced demodulators. |
| Logic Thresholds | 0.8V to 2.4V - guarantees direct interface with TTL/CMOS controllers without level-shifting circuitry. |
Pinout & Package
MAX4527ESA is housed in an 8-pin SO (Small Outline) package, 3.9mm × 4.9mm body, 1.27mm lead pitch, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Analog input/output terminal | Bidirectional node; connected to Y when IN = LOW, to X when IN = HIGH - forms one leg of phase-reversal path. |
| 2 (B) | Analog input/output terminal | Bidirectional node; connected to X when IN = LOW, to Y when IN = HIGH - complements A to complete bridge inversion. |
| 3 (GND) | Digital ground reference | Reference for logic inputs only; no analog signal path connection - enables separation of digital and analog return paths. |
| 4 (IN) | Logic control input | TTL/CMOS-compatible digital signal selecting phase state; accepts voltages from V− to V+ (no clamping diode to GND). |
| 5 (V−) | Negative analog supply | Sets lower analog rail limit; connect to GND for single-supply operation; internally biases P-channel switch gates. |
| 6 (Y) | Analog output/input terminal | Bidirectional node; output of inverted path (A→Y/B→X) when IN = LOW - used as balanced output in modulator circuits. |
| 7 (X) | Analog output/input terminal | Bidirectional node; output of non-inverted path (A→X/B→Y) when IN = LOW - paired with Y for differential output routing. |
| 8 (V+) | Positive analog/digital supply | Powers analog switches and internal logic; internally tied to substrate; sets upper analog rail and logic thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V− to V+ with full on-state conduction - eliminates level-shifting needs in ±15V sensor interfaces. |
| Guaranteed break-before-make | 1–5ns minimum interval prevents momentary shorting between X and Y during state transition - critical for avoiding signal transients in feedback loops. |
| 10pC max charge injection | Minimizes voltage step on sampling capacitors (e.g., in auto-zero ADCs), reducing settling time and offset drift. |
| 1µA supply current (MAX4527) | Enables use in always-on, low-duty-cycle portable instrumentation without compromising battery life. |
| 2kV ESD protection (HBM) | Withstands handling and board-level ESD events without latch-up or parameter shift - improves manufacturing yield and field reliability. |
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 | Identical electrical specs; packaged in 8-pin µMAX (3mm × 3mm) instead of SO - 40% smaller footprint, higher thermal resistance. | Better suited for space-constrained portable instruments; less optimal for manual prototyping due to fine-pitch leads. | Select MAX4527EUA when PCB area is critical and reflow assembly is available; retain MAX4527ESA for through-hole compatibility and thermal margin. |
| ADG1419BRUZ | Single 4:1 analog multiplexer (not phase-reversal); 4.5Ω RON, 1.5pC charge injection, but lacks bridge topology and guaranteed break-before-make. | Requires external wiring to emulate phase reversal - increases layout complexity and degrades AC balance vs. integrated bridge. | Choose ADG1419BRUZ only if channel count flexibility outweighs need for intrinsic phase-reversal symmetry and minimal charge injection. |
Compared with MAX4527EUA, MAX4527ESA offers superior thermal dissipation and easier hand-soldering, while ADG1419BRUZ trades integrated phase-reversal functionality for general-purpose multiplexing - making MAX4527ESA the optimal choice for chopper amp and modulator designs demanding intrinsic symmetry and low glitch energy.

FAQ
What is the operating temperature range for MAX4527ESA?
The MAX4527ESA is rated for −40°C to +85°C ambient operation, as confirmed in the Ordering Information table and Absolute Maximum Ratings section. This extended industrial temperature grade ensures reliable performance in harsh environments such as factory automation sensors and outdoor test equipment - unlike the commercial-grade MAX4527CSA (0°C to +70°C).
Does MAX4527ESA support single-supply operation?
Yes, MAX4527ESA supports single-supply operation from +4.5V to +36V by connecting V− to GND. The device maintains rail-to-rail analog signal handling (0V to V+), and all specifications - including 175Ω RON and 10pC charge injection - remain valid under this configuration, as verified in the Electrical Characteristics tables and Applications Information section.
How does MAX4527ESA differ from MAX4526ESA?
MAX4527ESA and MAX4526ESA share identical analog switch architecture and DC specifications (RON, leakage, charge injection), but differ in dynamic performance: MAX4527ESA uses a slower logic-level translator to achieve 1µA supply current, while MAX4526ESA prioritizes speed (250ns → 125ns transition time) at higher current draw - making MAX4527ESA optimal for battery-powered chopper amps where power efficiency outweighs raw speed.
Is MAX4527ESA pin-compatible with other packages in the same family?
Yes, MAX4527ESA (8-pin SO), MAX4527EPA (8-pin PDIP), and MAX4527EUA (8-pin µMAX) share identical pin numbering, function mapping, and electrical behavior - confirmed by the Pin Configuration table and Ordering Information. All three packages use the same die and bond wire layout, enabling drop-in replacement across form factors without schematic or layout changes.
What is the maximum analog signal frequency supported by MAX4527ESA?
MAX4527ESA is characterized for DC and low-frequency phase reversal up to 100kHz, as stated in the Applications Information section and validated by −65dB off-isolation at 1MHz and THD <0.01% at 1kHz. While usable beyond 100kHz, performance degrades due to internal capacitance imbalance - so MAX4527ESA is best applied in chopper amplifiers and audio-band modulators, not RF switching.
