Product details
Overview
MAX4527ESA+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 draws only 1µA supply current at +25°C - ideal for chopper-stabilized amplifiers requiring precision DC reversal.
For engineers reviewing the MAX4527ESA+T datasheet, MAX4527ESA+T pinout, MAX4527ESA+T application, or MAX4527ESA+T equivalent, key selection criteria include guaranteed break-before-make timing (1–5ns), 10pC max charge injection, ±15V-rated signal handling, TTL/CMOS-compatible logic thresholds (0.8V/2.4V), and SO-8 packaging for industrial-grade temperature operation (−40°C to +85°C).
Technical Context
The MAX4527ESA+T implements a fully differential bridge topology where analog inputs A and B are routed to outputs X and Y in either direct (IN = LOW) or inverted (IN = HIGH) polarity configuration. 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 four switch paths (A–X, A–Y, B–X, B–Y) share matched on-resistance (≤8Ω mismatch), flatness ≤12Ω, and <100ns transition time under ±15V supplies. Leakage remains ≤0.5nA at +25°C and ≤10nA at +85°C, with >2kV ESD protection per Method 3015.7 on all pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±18V dual or +4.5V to +36V single - supports industrial bipolar and wide-range unipolar systems |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation in precision DC/low-frequency 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 during switching |
| Transition Time | <100ns at ±15V - enables reliable operation up to 100kHz carrier frequencies |
| Supply Current | 1µA typical at +25°C - enables battery-powered or ultra-low-power chopper amplifier designs |
| Logic Thresholds | 0.8V (LOW), 2.4V (HIGH) - ensures robust TTL/CMOS compatibility across full supply range |
Pinout & Package
MAX4527ESA+T is housed in an 8-pin SO (Small Outline) package, 3.9mm × 4.9mm body, 1.27mm lead pitch, −40°C to +85°C operating range.
| 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 half of differential input pair |
| 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 paths are floating between V+ and V− |
| 4 (IN) | Logic control input | TTL/CMOS-compatible digital signal selecting direct/inverted routing mode |
| 5 (V−) | Negative analog supply | Sets lower analog signal limit; tied to GND for single-supply operation |
| 6 (Y) | Analog output terminal Y | Output node carrying phase-reversed or direct signal depending on IN state |
| 7 (X) | Analog output terminal X | Complementary output node to Y; completes differential output path |
| 8 (V+) | Positive analog/digital supply | Powers analog switches and logic; internally connected to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing fully from V− to V+, enabling use with ±15V op-amp stages without level-shifting |
| Guaranteed break-before-make | 1–5ns delay prevents momentary short-circuit between X and Y during polarity transition |
| 10pC max charge injection | Minimizes settling error in high-Z integrator or sample-hold circuits used in chopper amplifiers |

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+T | Higher supply current (1.5mA vs. 1µA); faster transition time (<250ns vs. <100ns); optimized for high-frequency operation | Better suited for carrier frequencies >100kHz; less suitable for ultra-low-power battery operation | Select MAX4526ESA+T when speed outweighs power constraints; verify thermal dissipation in compact layouts |
| ADG1419BRMZ | Single 4-throw SP4T architecture (not bridge); 4.5Ω RON; ±15V rating; no guaranteed break-before-make | Requires external logic to emulate phase reversal; higher RON mismatch may degrade carrier suppression | Use ADG1419BRMZ only when board space permits discrete bridge implementation and speed/power trade-offs allow |
Compared with MAX4527ESA+T, MAX4526ESA+T trades ultra-low quiescent current for higher speed, while ADG1419BRMZ offers lower on-resistance but lacks integrated bridge topology and break-before-make assurance - making MAX4527ESA+T optimal for precision, low-power chopper and modulator designs where topology and leakage are decisive.

FAQ
What is the maximum analog signal voltage range supported by the MAX4527ESA+T?
The MAX4527ESA+T supports analog signals from V− to V+, meaning it handles rail-to-rail operation across its full supply range. With ±15V supplies, this equals −15V to +15V; with +12V single supply (V− = GND), it supports 0V to +12V. Absolute maximum ratings allow V+ up to +44V and V− down to −25V, but functional operation is specified only within ±4.5V to ±18V dual or +4.5V to +36V single supply limits.
Does the MAX4527ESA+T require external pull-up or pull-down resistors on the IN pin?
No, the MAX4527ESA+T does not require external biasing on the IN pin. Its logic inputs have internally defined TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) and ESD protection diodes to V+ and V− - allowing direct connection to microcontroller GPIO, FPGA outputs, or logic gates without additional components. The input leakage is <1µA, ensuring compatibility with high-impedance drivers.
Can the MAX4527ESA+T be used with a single +5V supply?
Yes, the MAX4527ESA+T operates from a +4.5V to +36V single supply. For +5V operation, connect V− to GND, apply +5V to V+, and ensure analog signals remain within 0V to +5V. Note that on-resistance increases slightly at lower voltages (e.g., ~200Ω at +5V vs. 175Ω at ±15V), and leakage remains ≤0.5nA at +25°C - making it viable for low-voltage portable chopper circuits.
How does the break-before-make feature of the MAX4527ESA+T prevent signal corruption?
The MAX4527ESA+T guarantees a 1–5ns break-before-make interval during switching, ensuring that the old signal path disconnects completely before the new path connects. This eliminates momentary short-circuits between X and Y outputs - critical in phase-reversal applications where simultaneous conduction would collapse differential output voltage and inject large transient currents into downstream stages like integrators or transformers.
Is the MAX4527ESA+T pin-compatible with other devices in the MAX4526/MAX4527 family?
Yes, all MAX4526/MAX4527 variants - including MAX4527CPA, MAX4527CSA, MAX4527CUA, MAX4527EPA, MAX4527ESA, and MAX4527EUA - share identical 8-pin pinouts across DIP, SO, and µMAX packages. The MAX4527ESA+T (SO-8) is mechanically and electrically interchangeable with MAX4527CSA (commercial-temp SO-8) and MAX4527EUA (extended-temp µMAX), differing only in temperature grade and package footprint.
