Product details
Overview
MAX4526CUA+T from Maxim Integrated is a high-speed phase-reversal analog switch IC optimized for chopper-stabilized amplifiers and balanced modulators. 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, and features guaranteed break-before-make switching. Its 8-pin µMAX package supports compact, noise-isolated layouts in precision analog signal routing.
For engineers reviewing the MAX4526CUA+T datasheet, MAX4526CUA+T pinout, MAX4526CUA+T application, or MAX4526CUA+T equivalent, this page provides verified electrical parameters, real-world timing behavior under ±15V operation, leakage performance at temperature extremes, charge-injection limits critical for zero-drift systems, and validated alternative options for phase-reversal switching in chopper and modulation circuits.
Technical Context
The MAX4526CUA+T implements a bridge-configured analog switch with two normally open and two normally closed paths controlled by a single logic input (IN). Its internal CMOS topology uses complementary N- and P-channel MOSFETs driven out-of-phase by V+ and V− to enable true rail-to-rail signal handling without ground reference.
It features TTL/CMOS-compatible logic thresholds (0.8V to 2.4V), 10pC max charge injection, and <100ns transition time with ±15V supplies - characteristics confirmed for the MAX4526 variant and explicitly differentiated from the lower-power MAX4527 in both datasheet sections and typical operating curves.
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 and automotive single-supply systems. |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation and gain error in precision DC/low-frequency paths. |
| RON Matching (∆RON) | 8Ω max between A-X/A-Y/B-X/B-Y - critical for maintaining amplitude balance in differential phase-reversal applications. |
| Charge Injection | 10pC max - limits voltage glitch and settling error when switching high-impedance nodes (e.g., integrator inputs). |
| Transition Time | <100ns at ±15V - supports carrier frequencies up to 100kHz in balanced modulator/demodulator circuits. |
| Leakage Current | 0.5nA at +25°C, 10nA at +85°C - preserves accuracy in microamp-level bias and self-calibrating circuits. |
| Break-Before-Make Delay | 1ns to 5ns - prevents momentary short-circuiting of input sources during polarity reversal. |
Pinout & Package
MAX4526CUA+T is housed in an 8-pin µMAX package (2.1mm × 1.6mm, 0.5mm pitch), specified for 0°C to +70°C operation and featuring exposed pad thermal enhancement per Maxim's 21-0036D drawing.
| 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 leg of the phase-reversal bridge. |
| 2 (B) | Analog input terminal B | Connected to X when IN = LOW; to Y when IN = HIGH - complements A to enable polarity inversion. |
| 3 (GND) | Digital ground reference | Reference for logic circuitry only; analog paths are fully floating between V+ and V−. |
| 4 (IN) | Logic control input | TTL/CMOS-compatible (0.8V–2.4V thresholds); drives internal translator to select signal path configuration. |
| 5 (V−) | Negative analog supply | Sets lower rail for analog signals; tied to GND for single-supply use. |
| 6 (Y) | Analog output terminal Y | Output node for inverted or non-inverted signal depending on IN state; bidirectional, rail-to-rail capable. |
| 7 (X) | Analog output terminal X | Complementary output to Y; completes bridge topology for balanced signal routing. |
| 8 (V+) | Positive analog/digital supply | Powers analog switches and logic; internally connected to substrate; sets upper analog rail limit. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V− to V+ with no ground dependency - essential for isolated chopper amplifier feedback loops. |
| Guaranteed break-before-make | 1–5ns delay prevents cross-conduction during polarity switching - eliminates transient short-circuits in sensitive analog paths. |
| 10pC max charge injection | Minimizes voltage step errors at high-impedance nodes (e.g., op-amp integrators), enabling stable zero-drift operation. |
| 2pC max charge-injection match | Ensures matched transients across A/B paths - critical for common-mode rejection in differential chopper topologies. |
| >2kV ESD protection | Robustness per Method 3015.7 allows safe handling and board-level integration in test equipment and industrial environments. |
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 |
|---|---|---|---|
| MAX4527CUA+T | Same pinout and analog specs, but slower transition time (250ns vs. <100ns) and 1µA supply current vs. 1.5mA for MAX4526. | Optimized for low-power battery-operated systems where speed is secondary to quiescent current. | Select MAX4527CUA+T only when power budget is constrained and carrier frequency ≤50kHz. |
| ADG1419BRMZ | Single 8-pin SOIC, ±15V-rated, 1.5Ω RON, but lacks guaranteed break-before-make and has higher 25pC charge injection. | Used in general-purpose analog multiplexing, not validated for chopper amplifier symmetry or carrier suppression. | Choose ADG1419BRMZ only for non-critical polarity switching where ultra-low RON outweighs charge-injection and timing requirements. |
Compared with MAX4527CUA+T and ADG1419BRMZ, the MAX4526CUA+T uniquely combines high-speed phase reversal (<100ns), guaranteed break-before-make, and 10pC charge injection - making it the only option qualified for precision chopper-stabilized amplifiers requiring sub-microvolt offset cancellation.

FAQ
What is the operating temperature range for MAX4526CUA+T?
The MAX4526CUA+T is rated for 0°C to +70°C operation, as confirmed by its ordering code suffix 'C' and the 'MAX4526CUA' entry in the Ordering Information table. This commercial-grade range is validated across all electrical specifications including on-resistance, leakage, and transition time - unlike the extended −40°C to +85°C 'E' grade variants.
Does MAX4526CUA+T support single-supply operation?
Yes, the MAX4526CUA+T supports single-supply operation from +4.5V to +36V by connecting V− to GND. The datasheet explicitly states this in the General Description and Applications Information sections, and confirms rail-to-rail signal handling remains functional with V− grounded - critical for systems lacking negative rails.
What is the maximum analog signal voltage range supported by MAX4526CUA+T?
The MAX4526CUA+T supports analog signals from V− to V+, meaning ±15V with dual supplies or 0V to +15V with V− grounded. This is guaranteed by the Absolute Maximum Ratings table (V+ to V− ≤ +44V) and Electrical Characteristics section, where VA/VB/VX/VY analog-signal range is specified as V− to V+.
Is MAX4526CUA+T pin-compatible with MAX4527CUA+T?
Yes, MAX4526CUA+T and MAX4527CUA+T share identical 8-pin µMAX packaging, pin functions, and pinout - confirmed by the Pin Configuration diagram and Ordering Information tables listing both parts with identical 'CUA' suffix and package type. However, their internal logic drivers differ, affecting speed and supply current.
What is the purpose of the break-before-make feature in MAX4526CUA+T?
The break-before-make feature in MAX4526CUA+T enforces a 1–5ns delay between opening one switch path and closing the other, preventing momentary short-circuits between A/B inputs during polarity reversal. This is essential in chopper and modulator applications to avoid signal corruption, latch-up, or damage to upstream sources.
