Product details
Overview
MAX4527EUA+T 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, handles rail-to-rail analog signals (V− to V+), and consumes only 1µA at +25°C - optimized for chopper-stabilized amplifiers and self-calibrating circuits.
For engineers reviewing the MAX4527EUA+T datasheet, MAX4527EUA+T pinout, MAX4527EUA+T application, or MAX4527EUA+T equivalent, key selection criteria include guaranteed break-before-make timing (1–5ns), 10pC max charge injection, rail-to-rail signal handling, TTL/CMOS-compatible logic thresholds (0.8V/2.4V), and −40°C to +85°C industrial temperature rating in an 8-pin µMAX package.
Technical Context
The MAX4527EUA+T implements a fully differential bridge topology where analog inputs A/B are routed to outputs X/Y under logic control of the IN pin, enabling true polarity inversion without external components. Its internal logic-level translator drives N- and P-channel MOSFET gates with out-of-phase signals referenced to V+ and V−, ensuring symmetrical conduction and minimal DC offset.
Unlike standard analog switches, it guarantees break-before-make switching to prevent momentary shorting during state transitions, and its ESD protection (>2kV per Method 3015.7) is integrated on all pins except GND. Leakage current remains below 0.5nA at +25°C and 10nA at +85°C, supporting precision DC-coupled applications requiring long-term stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±18V dual or +4.5V to +36V single - supports bipolar sensor interfaces and single-supply industrial systems |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation in precision gain paths |
| RON Matching | 8Ω max between A-X/A-Y/B-X/B-Y - critical for balanced modulator carrier suppression |
| Charge Injection | 10pC max - limits voltage glitch on high-impedance nodes like integrator capacitors |
| Leakage Current | 0.5nA max at +25°C - enables >100GΩ effective input impedance in zero-drift amplifier feedback loops |
| Transition Time | 250ns max at ±15V - suitable for <100kHz chopper frequencies with predictable timing margins |
| Logic Thresholds | 0.8V low / 2.4V high - ensures reliable interface with 3.3V/5V microcontrollers without level shifters |
Pinout & Package

| 2 (B) | Analog input terminal B | Connected to X when IN = LOW; to Y when IN = HIGH - complementary to A for phase reversal |
| 3 (GND) | Digital ground reference | Reference for logic circuitry only; analog path is floating between V+ and V− |
| 4 (IN) | Logic control input | TTL/CMOS-compatible; controls switch state with guaranteed break-before-make timing |
| 5 (V−) | Negative analog supply | Sets lower analog signal limit; connect to GND for single-supply operation |
| 6 (Y) | Analog output terminal Y | Output node for inverted or non-inverted signal depending on IN state |
| 7 (X) | Analog output terminal X | Complementary output to Y; completes differential output pair |
| 8 (V+) | Positive analog/digital supply | Powers analog switches and logic; internally connected to substrate |

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+T | Higher supply current (1.5mA vs. 1µA); faster transition time (95ns vs. 250ns); same pinout and RON specs | Better suited for >100kHz chopper frequencies but increases power budget | Select MAX4526EUA+T only when speed outweighs power constraints |
| ADG1419BRMZ | Single SPDT switch (not bridge); 1.5Ω RON; requires external wiring for phase reversal; no guaranteed break-before-make | Needs discrete layout for polarity inversion; higher design complexity and reduced symmetry | Choose ADG1419BRMZ only if ultra-low RON is mandatory and bridge functionality can be implemented externally |
Compared with MAX4526EUA+T, the MAX4527EUA+T trades speed for 1500× lower quiescent current while retaining identical analog performance and pin compatibility; versus ADG1419BRMZ, it delivers integrated bridge topology and guaranteed break-before-make - reducing PCB area and improving AC balance without external components.

FAQ
What is the operating temperature range for the MAX4527EUA+T?
The MAX4527EUA+T is rated for −40°C to +85°C, making it suitable for industrial environments where ambient temperatures exceed commercial-grade limits. This extended range is confirmed in the Ordering Information table and validated across all electrical specifications including leakage current, on-resistance, and transition time - unlike the C-grade variants limited to 0°C to +70°C.
Does the MAX4527EUA+T support single-supply operation?
Yes, the MAX4527EUA+T supports single-supply operation from +4.5V to +36V by connecting the V− pin to GND. The device maintains rail-to-rail analog signal handling (0V to V+) and retains all key specs including 175Ω max on-resistance and 0.5nA leakage at +25°C. Power-supply considerations in the datasheet explicitly confirm safe single-supply use with proper bypassing.
How does the MAX4527EUA+T achieve phase reversal?
The MAX4527EUA+T achieves phase reversal via an internal bridge configuration: when the IN pin is LOW, A connects to Y and B connects to X; when IN is HIGH, A connects to X and B connects to Y. This cross-switching action inverts the differential relationship between inputs and outputs - enabling true polarity reversal without external op-amps or transformers, as verified in the Truth Table and Figure 1.
Is the MAX4527EUA+T pin-compatible with the MAX4526EUA+T?
Yes, the MAX4527EUA+T is pin-compatible with the MAX4526EUA+T - both share identical 8-pin µMAX packaging, pin assignments, and absolute maximum ratings. The only functional differences are supply current (1µA vs. 1.5mA) and transition time (250ns vs. 95ns), allowing direct substitution where low-power operation is prioritized over speed.
What is the significance of guaranteed break-before-make in the MAX4527EUA+T?
Guaranteed break-before-make (1–5ns) in the MAX4527EUA+T ensures that one switch path fully opens before the other closes - preventing momentary short-circuits between A/B and X/Y during state transitions. This is critical in bridge configurations to avoid signal corruption, thermal stress, or latch-up, and is explicitly characterized in the Electrical Characteristics table under tBBM parameter.
