Product details
Overview
MAX4528EUA from Maxim Integrated is a low-voltage, phase-reversal analog switch configured as a bridge-switch IC for precision DC and low-frequency signal inversion. It operates from ±2.7V to ±6V dual supplies or +2.7V to +12V single supply, delivers 110Ω max on-resistance (±5V), 5pC max charge injection, <100ns transition time, and supports rail-to-rail analog signals from V− to V+. It is used in chopper-stabilized amplifiers requiring precise polarity reversal without signal grounding.
For engineers reviewing the MAX4528EUA datasheet, MAX4528EUA pinout, MAX4528EUA application, or MAX4528EUA equivalent, key selection criteria include on-resistance matching (≤7Ω), leakage current (0.5nA @ +25°C), logic-level compatibility (0.8V–2.4V thresholds), ESD rating (>2kV), and µMAX-8 package suitability for space-constrained chopper and modulator designs.
Technical Context
The MAX4528EUA implements a fully integrated bridge configuration of two normally open and two normally closed CMOS switches, enabling true differential phase reversal with continuous DC path integrity and high off-isolation (>68dB). Its internal logic-level translator drives N- and P-channel MOSFET gates out-of-phase using V+ and V−, eliminating ground reference for analog paths.
It is characterized for ±5V operation but maintains functional performance across its full supply range; analog signal handling remains rail-to-rail (V− to V+), while digital inputs retain TTL/CMOS compatibility independent of V− level. Charge injection (≤5pC) and on-resistance flatness (≤15Ω) are optimized for chopper amplifier zeroing accuracy and low-distortion modulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2.7V to ±6V dual or +2.7V to +12V single - enables flexible biasing in isolated or single-rail systems |
| On-Resistance (RON) | 110Ω max (±5V) - ensures minimal signal attenuation and gain error in precision DC paths |
| On-Resistance Match (∆RON) | 7Ω max - critical for balanced signal paths in chopper amplifiers and modulators |
| Charge Injection | 5pC max - limits voltage glitch and settling error during switching in auto-zeroing circuits |
| Transition Time | <100ns (±5V) - supports carrier frequencies up to 100kHz in balanced modulator applications |
| Leakage Current | 0.5nA @ +25°C, 20nA @ +85°C - preserves DC accuracy in high-impedance sensor interfaces |
| Logic Thresholds | VINH = 1.6–2.4V, VINL = 0.8–1.6V - guarantees reliable TTL/CMOS drive without external level-shifting |
Pinout & Package
MAX4528EUA is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), specified for −40°C to +85°C operation. The package features exposed pad for thermal enhancement and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 A | Analog input/output terminal | Connected to Y when IN = LOW; to X when IN = HIGH - forms one half of phase-reversal path |
| 2 B | Analog input/output terminal | Connected to X when IN = LOW; to Y when IN = HIGH - complementary path to A for bridge inversion |
| 3 GND | Digital ground reference | Reference for logic circuitry only; analog paths are floating between V+ and V−, not referenced to GND |
| 4 IN | Logic control input | TTL/CMOS-compatible control pin; accepts voltages from V− to V+; no GND-referenced ESD diodes |
| 5 V− | Negative analog supply | Set to GND for single-supply operation; defines lower bound of rail-to-rail analog signal range |
| 6 Y | Analog output/input terminal | Output when IN = LOW (A→Y, B→X); output when IN = HIGH (B→Y, A→X) - inverted path endpoint |
| 7 X | Analog output/input terminal | Output when IN = LOW (B→X, A→Y); output when IN = HIGH (A→X, B→Y) - non-inverted path endpoint |
| 8 V+ | Positive analog/digital supply | Internally connected to substrate; powers analog switches and logic; sets upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output signals spanning V− to V+, enabling full dynamic range use in bipolar and single-supply systems |
| 5pC max charge injection | Minimizes transient voltage errors during switching - essential for chopper amplifier offset cancellation fidelity |
| >2kV ESD protection (HBM) | Ensures robustness during board handling and system integration without external protection components |
| Break-before-make timing | 1–20ns delay prevents momentary short-circuit between signal paths during state transitions |
| 1.0µA max supply current | Reduces quiescent power in battery-operated or thermally constrained instrumentation designs |

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 |
|---|---|---|---|
| MAX4526ESA | Same architecture, but rated for 0°C to +70°C only; 8-SO package; slightly higher RON (120Ω max @ ±5V) | Limited temperature range reduces suitability for industrial environments; SO package increases board area vs. µMAX | Select when cost sensitivity outweighs extended temperature or size requirements |
| ADG1419BRMZ | Single 2:1 SPDT switch (not bridge); 0.5Ω RON; requires external wiring for phase reversal; ±15V capable | Not functionally identical - lacks integrated bridge topology and automatic polarity inversion logic | Choose only if discrete bridge implementation is acceptable and ultra-low RON is prioritized over integration |
Compared with MAX4526ESA and ADG1419BRMZ, the MAX4528EUA uniquely integrates a complete phase-reversal bridge in a single µMAX-8 package with guaranteed −40°C to +85°C operation, eliminating external routing complexity and ensuring matched path performance critical for chopper and modulator stability.

FAQ
What is the operating temperature range for MAX4528EUA?
The MAX4528EUA is specified for −40°C to +85°C operation, making it suitable for industrial and automotive-adjacent applications where ambient conditions exceed commercial-grade limits. This extended range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet, distinguishing it from the C-grade (0°C to +70°C) variants like MAX4528CUA.
Can MAX4528EUA operate from a single +3.3V supply?
Yes, MAX4528EUA supports single-supply operation from +2.7V to +12V. At +3.3V, typical on-resistance rises to ~250Ω (min)–900Ω (max), and transition time extends to 150–400ns - values documented in the +3V Single Supply Electrical Characteristics table. V− must be tied to GND, and logic thresholds adjust accordingly (VINL = 0.6–0.9V, VINH = 0.9–2.4V).
Does MAX4528EUA require external pull-up or pull-down resistors on the IN pin?
No, MAX4528EUA does not require external biasing on the IN pin. Its logic inputs feature internally defined TTL/CMOS-compatible thresholds (0.8V–2.4V) and ESD protection diodes to V+ and V− - not GND - allowing direct connection to microcontroller GPIO or FPGA outputs without additional components.
How is analog signal grounding handled in MAX4528EUA circuits?
MAX4528EUA analog paths (A, B, X, Y) have no internal GND reference; they operate fully floating between V+ and V−. GND pin serves logic only. For proper operation, external circuitry must provide a DC path to GND - e.g., via center-tapped transformer, high-value resistor divider, or intentional bias network - to ensure symmetrical switch conduction and minimize leakage-induced offset.
What is the maximum carrier frequency supported by MAX4528EUA in modulator applications?
MAX4528EUA is optimized for carrier frequencies up to 100kHz in balanced modulator configurations, as stated in the Applications Information section. Performance degrades above this due to increasing impact of internal capacitance/resistance imbalances; measured off-isolation drops from >68dB at DC to ~−40dB at 1MHz, confirming its design focus on low-frequency precision rather than RF switching.
