Product details
Overview
MAX4527CSA from Maxim Integrated is a low-power, phase-reversal analog switch IC configured as a bridge-switch array with two normally open and two normally closed CMOS switches. It operates from +4.5V to +36V single supply or ±4.5V to ±18V dual supplies, delivers 175Ω max on-resistance (±15V), <100ns transition time, and rail-to-rail signal handling. It is optimized for chopper-stabilized amplifiers and balanced modulators requiring precise polarity inversion.
For engineers reviewing the MAX4527CSA datasheet, MAX4527CSA pinout, MAX4527CSA application, or MAX4527CSA equivalent, this page provides verified pin functions, real-world leakage specs (0.5nA @ +25°C), charge injection (10pC max), break-before-make timing (1–5ns), and validated alternatives for low-power phase-reversal signal routing in precision analog systems.
Technical Context
The MAX4527CSA implements a fully differential bridge topology where logic-controlled IN pin selects between two complementary signal paths: A→Y/B→X (IN = LOW) or A→X/B→Y (IN = HIGH). Its internal N- and P-channel MOSFETs are driven out-of-phase by V+ and V−, enabling true rail-to-rail analog conduction without ground reference.
All analog terminals (A, B, X, Y) support bidirectional signal flow with matched on-resistance (≤8Ω mismatch) and guaranteed break-before-make switching. Input logic thresholds (0.8V/2.4V) ensure TTL/CMOS compatibility across its full supply range, and ESD protection exceeds 2kV per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +4.5V to +36V single or ±4.5V to ±18V dual - supports industrial and bipolar signal conditioning rails |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal gain error and voltage drop in precision DC/low-frequency paths |
| On-Resistance Match (∆RON) | 8Ω max - critical for maintaining amplitude balance in chopper and modulator applications |
| Charge Injection | 10pC max - limits offset voltage step during switching in auto-zeroing and self-calibrating circuits |
| Transition Time | <100ns at ±15V - enables reliable operation up to ~100kHz carrier frequencies in modulators |
| Leakage Current | 0.5nA max @ +25°C - preserves high-impedance node integrity in sensitive front-end stages |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in bench-test and production handling environments |
Pinout & Package
MAX4527CSA is housed in an 8-pin SO (Small Outline) package, 150-mil body width, with gull-wing leads and standard JEDEC MS-012AC footprint.
| 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 - complements A for balanced phase reversal |
| 3 GND | Digital ground reference | Reference for logic circuitry only; analog path is floating between V+ and V− - prevents digital noise coupling |
| 4 IN | Logic-level control input | TTL/CMOS-compatible (0.8V/2.4V thresholds); controls switch state - no external level-shifting required |
| 5 V− | Negative analog supply | Set to GND for single-supply use; defines lower rail of analog signal range - must be bypassed with 0.1µF ceramic |
| 6 Y | Analog output terminal Y | Output node for inverted or non-inverted path depending on IN - bidirectional, rail-to-rail capable |
| 7 X | Analog output terminal X | Complementary output to Y - used with Y to deliver balanced differential output signals |
| 8 V+ | Positive analog/digital supply | Powers both analog switches and logic translator; internally tied to substrate - requires local 0.1µF bypass |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V− to V+ with no ground reference - enables true bipolar operation in isolated signal chains |
| Guaranteed break-before-make | 1–5ns minimum delay prevents momentary short-circuit between X/Y outputs - essential for avoiding signal glitches |
| 10pC max charge injection | Minimizes voltage transient on high-Z nodes during switching - critical for chopper amplifier offset cancellation |
| 2pC max charge-injection match | Ensures matched transients across A/B paths - preserves common-mode rejection in balanced architectures |
| 1µA supply current (MAX4527) | Enables battery-powered or ultra-low-power instrumentation designs where standby current matters |
Applications

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 | Identical electrical specs; packaged in 8-pin µMAX (3mm × 3mm) instead of SO - 40% smaller footprint | Better suited for space-constrained portable or wearable instrumentation where board area is critical | Select MAX4527CUA when PCB real estate is limited and thermal dissipation allows µMAX package use. |
| ADG1419BRUZ | Higher on-resistance (2.7Ω typ), wider supply (±15V only), but superior charge injection match (0.5pC) and 12-bit AC accuracy | Preferred in high-precision data acquisition where THD and harmonic distortion matter more than power | Choose ADG1419BRUZ when system-level AC performance (e.g., THD < −100dB) outweighs low-quiescent-current requirements. |
Compared with MAX4527CSA, MAX4527CUA offers identical functionality in a smaller package for compact designs, while ADG1419BRUZ trades higher supply current for significantly better AC matching and lower distortion-making it suitable for metrology-grade signal chains where precision supersedes power efficiency.

FAQ
What is the operating temperature range for MAX4527CSA?
The MAX4527CSA is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is validated across all key parameters including on-resistance, leakage current, and transition time. The device uses the same silicon die as the extended-range MAX4527ESA (−40°C to +85°C), but MAX4527CSA undergoes screening and testing only within the 0°C to +70°C specification band.
Can MAX4527CSA operate from a single +5V supply?
Yes, MAX4527CSA can operate from a +5V single supply by connecting V− to GND. However, on-resistance increases significantly at low voltages - typical RON rises to ~300Ω at +5V (vs. 175Ω at ±15V). For optimal performance in precision applications, use ≥±12V or +24V supplies. The logic thresholds remain valid down to +4.5V.
Is MAX4527CSA pin-compatible with MAX4526CSA?
Yes, MAX4527CSA and MAX4526CSA share identical pinout, package, and footprint. They differ only in internal logic driver speed and quiescent current: MAX4526CSA draws ~1.5mA and achieves faster transition time (<250ns), while MAX4527CSA draws 1µA and targets low-power operation. Substitution is electrically safe but alters dynamic performance.
Does MAX4527CSA require external pull-up or pull-down resistors on the IN pin?
No, MAX4527CSA does not require external biasing on the IN pin. Its TTL/CMOS-compatible input has defined logic thresholds (0.8V low, 2.4V high) and sufficient noise margin across its full supply range. Driving IN directly from a microcontroller GPIO or logic gate is sufficient - no pull resistors needed unless the source is open-drain or high-impedance.
How is rail-to-rail signal handling achieved in MAX4527CSA without a ground reference?
MAX4527CSA achieves rail-to-rail operation by using complementary N- and P-channel MOSFETs whose gates are driven by V+ and V−, respectively. The analog path floats between V+ and V−, with no DC path to GND. Signals from V− to V+ pass unattenuated because the switch channel remains conductive across the full range - confirmed by characterization showing <0.1% RON variation over ±15V.
